+ *
+ * \brief Timing synchronizer using polyphase filterbanks
+ *
+ * \ingroup filter_blk
+ * \ingroup pfb_blk
+ *
+ * This block performs timing synchronization for PAM signals by
+ * minimizing the derivative of the filtered signal, which in turn
+ * maximizes the SNR and minimizes ISI.
+ *
+ * This approach works by setting up two filterbanks; one filterbank
+ * contains the signal's pulse shaping matched filter (such as a root
+ * raised cosine filter), where each branch of the filterbank contains
+ * a different phase of the filter. The second filterbank contains
+ * the derivatives of the filters in the first filterbank. Thinking of
+ * this in the time domain, the first filterbank contains filters that
+ * have a sinc shape to them. We want to align the output signal to be
+ * sampled at exactly the peak of the sinc shape. The derivative of
+ * the sinc contains a zero at the maximum point of the sinc (sinc(0)
+ * = 1, sinc(0)' = 0). Furthermore, the region around the zero point
+ * is relatively linear. We make use of this fact to generate the
+ * error signal.
+ *
+ * If the signal out of the derivative filters is d_i[n] for the ith
+ * filter, and the output of the matched filter is x_i[n], we
+ * calculate the error as: e[n] = (Re{x_i[n]} * Re{d_i[n]} +
+ * Im{x_i[n]} * Im{d_i[n]}) / 2.0 This equation averages the error in
+ * the real and imaginary parts. There are two reasons we multiply by
+ * the signal itself. First, if the symbol could be positive or
+ * negative going, but we want the error term to always tell us to go
+ * in the same direction depending on which side of the zero point we
+ * are on. The sign of x_i[n] adjusts the error term to do
+ * this. Second, the magnitude of x_i[n] scales the error term
+ * depending on the symbol's amplitude, so larger signals give us a
+ * stronger error term because we have more confidence in that
+ * symbol's value. Using the magnitude of x_i[n] instead of just the
+ * sign is especially good for signals with low SNR.
+ *
+ * The error signal, e[n], gives us a value proportional to how far
+ * away from the zero point we are in the derivative signal. We want
+ * to drive this value to zero, so we set up a second order loop. We
+ * have two variables for this loop; d_k is the filter number in the
+ * filterbank we are on and d_rate is the rate which we travel through
+ * the filters in the steady state. That is, due to the natural clock
+ * differences between the transmitter and receiver, d_rate represents
+ * that difference and would traverse the filter phase paths to keep
+ * the receiver locked. Thinking of this as a second-order PLL, the
+ * d_rate is the frequency and d_k is the phase. So we update d_rate
+ * and d_k using the standard loop equations based on two error
+ * signals, d_alpha and d_beta. We have these two values set based on
+ * each other for a critically damped system, so in the block
+ * constructor, we just ask for "gain," which is d_alpha while d_beta
+ * is equal to (gain^2)/4.
+ *
+ * The block's parameters are:
+ *
+ * \li \p sps: The clock sync block needs to know the number of samples per
+ * symbol, because it defaults to return a single point representing
+ * the symbol. The sps can be any positive real number and does not
+ * need to be an integer.
+ *
+ * \li \p loop_bw: The loop bandwidth is used to set the gain of the
+ * inner control loop (see:
+ * http://gnuradio.squarespace.com/blog/2011/8/13/control-loop-gain-values.html).
+ * This should be set small (a value of around 2pi/100 is suggested in
+ * that blog post as the step size for the number of radians around
+ * the unit circle to move relative to the error).
+ *
+ * \li \p taps: One of the most important parameters for this block is
+ * the taps of the filter. One of the benefits of this algorithm is
+ * that you can put the matched filter in here as the taps, so you get
+ * both the matched filter and sample timing correction in one go. So
+ * create your normal matched filter. For a typical digital
+ * modulation, this is a root raised cosine filter. The number of taps
+ * of this filter is based on how long you expect the channel to be;
+ * that is, how many symbols do you want to combine to get the current
+ * symbols energy back (there's probably a better way of stating
+ * that). It's usually 5 to 10 or so. That gives you your filter, but
+ * now we need to think about it as a filter with different phase
+ * profiles in each filter. So take this number of taps and multiply
+ * it by the number of filters. This is the number you would use to
+ * create your prototype filter. When you use this in the PFB
+ * filerbank, it segments these taps into the filterbanks in such a
+ * way that each bank now represents the filter at different phases,
+ * equally spaced at 2pi/N, where N is the number of filters.
+ *
+ * \li \p filter_size (default=32): The number of filters can also be
+ * set and defaults to 32. With 32 filters, you get a good enough
+ * resolution in the phase to produce very small, almost unnoticeable,
+ * ISI. Going to 64 filters can reduce this more, but after that
+ * there is very little gained for the extra complexity.
+ *
+ * \li \p init_phase (default=0): The initial phase is another
+ * settable parameter and refers to the filter path the algorithm
+ * initially looks at (i.e., d_k starts at init_phase). This value
+ * defaults to zero, but it might be useful to start at a different
+ * phase offset, such as the mid-point of the filters.
+ *
+ * \li \p max_rate_deviation (default=1.5): The next parameter is the
+ * max_rate_devitation, which defaults to 1.5. This is how far we
+ * allow d_rate to swing, positive or negative, from 0. Constraining
+ * the rate can help keep the algorithm from walking too far away to
+ * lock during times when there is no signal.
+ *
+ * \li \p osps (default=1): The osps is the number of output samples per symbol. By default,
+ * the algorithm produces 1 sample per symbol, sampled at the exact
+ * sample value. This osps value was added to better work with
+ * equalizers, which do a better job of modeling the channel if they
+ * have 2 samps/sym.

+ * \li \p loop_bw: The loop bandwidth is used to set the gain of the
+ * inner control loop (see:
+ * http://gnuradio.squarespace.com/blog/2011/8/13/control-loop-gain-values.html).
+ * This should be set small (a value of around 2pi/100 is suggested in
+ * that blog post as the step size for the number of radians around
+ * the unit circle to move relative to the error).
+ *
+ * \li \p taps: One of the most important parameters for this block is
+ * the taps of the filter. One of the benefits of this algorithm is
+ * that you can put the matched filter in here as the taps, so you get
+ * both the matched filter and sample timing correction in one go. So
+ * create your normal matched filter. For a typical digital
+ * modulation, this is a root raised cosine filter. The number of taps
+ * of this filter is based on how long you expect the channel to be;
+ * that is, how many symbols do you want to combine to get the current
+ * symbols energy back (there's probably a better way of stating
+ * that). It's usually 5 to 10 or so. That gives you your filter, but
+ * now we need to think about it as a filter with different phase
+ * profiles in each filter. So take this number of taps and multiply
+ * it by the number of filters. This is the number you would use to
+ * create your prototype filter. When you use this in the PFB
+ * filerbank, it segments these taps into the filterbanks in such a
+ * way that each bank now represents the filter at different phases,
+ * equally spaced at 2pi/N, where N is the number of filters.
+ *
+ * \li \p filter_size (default=32): The number of filters can also be
+ * set and defaults to 32. With 32 filters, you get a good enough
+ * resolution in the phase to produce very small, almost unnoticeable,
+ * ISI. Going to 64 filters can reduce this more, but after that
+ * there is very little gained for the extra complexity.
+ *
+ * \li \p init_phase (default=0): The initial phase is another
+ * settable parameter and refers to the filter path the algorithm
+ * initially looks at (i.e., d_k starts at init_phase). This value
+ * defaults to zero, but it might be useful to start at a different
+ * phase offset, such as the mid-point of the filters.
+ *
+ * \li \p max_rate_deviation (default=1.5): The next parameter is the
+ * max_rate_devitation, which defaults to 1.5. This is how far we
+ * allow d_rate to swing, positive or negative, from 0. Constraining
+ * the rate can help keep the algorithm from walking too far away to
+ * lock during times when there is no signal.
+ *
+ * \li \p osps (default=1): The osps is the number of output samples
+ * per symbol. By default, the algorithm produces 1 sample per symbol,
+ * sampled at the exact sample value. This osps value was added to
+ * better work with equalizers, which do a better job of modeling the
+ * channel if they have 2 samps/sym.
