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 (85ed61b6f26f2a24473b2e39612b3d8843dacba0) \ N -- N -- N (eb49690a31394681840f61e1df49089d005e5852) 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=eb49690a31394681840f61e1df49089d005e5852 commit eb49690a31394681840f61e1df49089d005e5852 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.

Add string descriptions for just a bit more sanity.

The motivation is to provide a facility for diversity and/or MIMO burst handling. When no channel value is specified, single channel bevhaviour is maintained.

We can avoid this extra copy constructor with a pointer reference and dynamic allocation.

Internally, the delay call creates a new vector and copies the contents back into the original. Instead, provide the option to return the computed output vector directly and remove an an extra copy in the process.

Simplify the sinc() function with a dedicated table lookup. Eventually, this table may be removed in favour of using a precomputed filterbank for fractional delay determination.
