Channelizer can now produce any rational ratio of the sample rate in [fs/N, 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].

Tom Rondeau [Fri, 9 Apr 2010 04:40:36 +0000 (00:40 -0400)]
Every other time through the channelizer, the FFT input buffer must be 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.

Working version of channelizer allowing an integer multiple of the sampling 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.

Add new block gr.additive_scrambler_bb()
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.
