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.

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.
