The burst search order is 8-PSK first followed by GMSK. EDGE will force 4 SPS sampling on Tx and Rx. Along with twice the search correlation from 8-PSK and GMSK, EDGE will increase CPU utilization. Whether the increase is notable or not is dependent on the particular machine.

Length is the sole factor in determining whether to modulate a bit vector using GMSK or 8-PSK. Tested with 8-PSK training sequences with random payload originating from osmo-bts. Output verified with Agilent E4406A.

For the latter, we now require at least 5 samples (rather than 2) to compute a peak-to-average value. End result is increased burst detection at low SNR conditions with a small increase in false positive bursts when no signal is present.

Only USRP B200/B210 devices are supported because of sample rate requirements (3.2 Msps). Only 4 SPS operation Tx/RX is supported. 8-PSK is supported. Other options may be added at a later time Signed-off-by: Tom Tsou <tom.tsou(a)ettus.com> http://cgit.osmocom.org/osmo-trx/commit/?id=35222296fef378977a83a4ee89d8c3e… commit 35222296fef378977a83a4ee89d8c3ef9bc62a3f Author: Tom Tsou <tom.tsou(a)ettus.com> Date: Wed Jun 22 16:16:30 2016 -0700 mcbts: Add multi-ARFCN channelizing filters Introduce polyphase channelizer (Rx) and synthesis (Tx) filterbanks, which serve as the signal processing backend for multi-carrier GSM. Fast Fourier Transform (FFT) is used internally. FFTW is added as a new build dependency.

The outer buffer interfaces with the device receive interface to guarantee timestamp aligned and contiguously allocated sample buffers. The inner buffer absorbs vector size differences between GSM bursts (156 or 157 samples) and the resampler interface (typically fixed multiples of 65). Reimplement the inner buffer with a ring buffer that allows fixed size segments on the outer (resampler) portion and variable lengths (GSM side) on the inner side. Compared to the previous stack-like version, this implementation removes unnecessary copying of buffer contents.
