That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (9532ac5c9eeef75ab3ddd4f750357a26953d6f44) \ N -- N -- N (85ed61b6f26f2a24473b2e39612b3d8843dacba0) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/osmo-trx/commit/?id=85ed61b6f26f2a24473b2e39612b3d8843dacba0 commit 85ed61b6f26f2a24473b2e39612b3d8843dacba0 Author: Thomas Tsou Date: Wed Nov 13 23:38:09 2013 -0500 Transceiver52M: Add dual channel diversity receiver option This patch add support for dual channel diversity on the receive path. This allows two antennas two shared antennas to be used for each ARFCN handling channel in the receiver. This configuration may improvde performance in multi-path fading environments, however, noise andpotential interference levels are increased due to the higher bandwidth used. The receive path is oversampled by a factor of four for a rate of 1.083333 Msps. If the receive paths are tuned within a maximum channel spacing (currently set at 600 kHz), then both ARFCN frequencies are processed by each channel of the receiver. Otherwise, the frequency shifted diversity path is disabled and standard non-diversity operation takes place. Diversity processing is handled by selecting the path with the higheset energy level and discarding the burst on the second path. Selection occurs on a burst-by-burst basis.

Break out RACH, normal burst, and demodulation into separate methods. This makes the burst handling from the FIFO read to soft bit output somewhat more manageable.

With continuously increasing phase, this leads to an eventual permanent hard spin. Wrap the phase value to prevent that from happening.

Avoid both cases by dynamically allocating with preloaded head room. The latter provides enough memory before the first sample in the burst to cover the length of the filter taps.
