2010-04-12Reworking variables to avoid recalculations/assignments.Tom Rondeau
2010-04-12Channelizer can now produce any rational ratio of the sample rate in [fs/N, ↵Tom Rondeau
fs] where fs is the input sample rate and N is the number of channels. The ratios work out to be N/i for i in [1, N].
2010-04-12Moving towards gr_block implementation to enable non-integer output rates. ↵Tom Rondeau
Also, cleaning up a bit wrt class members.
2010-04-11Removed omnithreads dependency from libusrp2Johnathan Corgan
2010-04-09Every other time through the channelizer, the FFT input buffer must be ↵Tom Rondeau
flipped. The commented code removed in this checkin does that through a calculation in the loops, but the way the filter assignment works with this code, the flip is done by keeping the indexing static, so a look up table works and is slightly faster.
2010-04-09Removing other version of code for different sample rates.Tom Rondeau
2010-04-09Working version of channelizer allowing an integer multiple of the sampling ↵Tom Rondeau
rate out. There are two versions of the code in here with the second way being more general and efficient. This one should be more extendable to allowing rational ratio output sampling rates.
2010-04-07Opening up channelizer to have different sampling rates out. This first pass ↵Tom Rondeau
produces the correct output for oversampling_rate = 1.

too much to render, ie use truncation)
2010-03-21Add new block gr.additive_scrambler_bb()Johnathan Corgan
This block performs scrambling by XORing the input sequence with the output of an LFSR. Repeating this operation restores the original sequence. (This differs from gr.scrambler_bb(), which convolves the input sequence with the LFSR output.) The additive scrambler allows an optional bit count after which the LFSR is reset to its initial seed. This allows use with, e.g., packetized fixed length payloads.

the gnuradio python namespace, but rather in the howto namespace. This allows it to be installed under a separate --prefix in the common case where the user doing the "out of tree build" is going to be installing their new and/or modified code somewhere other than the system installation directories. Any code that uses these blocks should now import them using: import howto instead of from gnuradio import howto
