It was generated because a ref change was pushed to the repository containing the project "OpenBTS' transceiver retro-fit". The branch, staging has been updated discards eb49690a31394681840f61e1df49089d005e5852 (commit) via 15d72ad64133686499bf8634e7cc867cbcee9995 (commit) This update added new revisions after undoing existing revisions. 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 (eb49690a31394681840f61e1df49089d005e5852) \ N -- N -- N (15d72ad64133686499bf8634e7cc867cbcee9995) 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=15d72ad64133686499bf8634e7cc867cbcee9995 commit 15d72ad64133686499bf8634e7cc867cbcee9995 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.
