This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "OpenBTS' transceiver retro-fit".

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 (fe3714a217f469182099118fc3ce5c730008caeb)
             N -- N -- N (7fec3030d46b2c35c34d90507feab253cddb9c01)

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.

commit 7fec3030d46b2c35c34d90507feab253cddb9c01
Author: Tom Tsou <tom.tsou at ettus.com>
Date:   Sun Mar 6 22:33:20 2016 -0800

    EDGE: Combine shared GMSK and 8-PSK demodulator sections
    Timing recovery and single tap channel compensation are identical
    in both GMSK and EDGE receivers. This is the section ahead of and
    including the optional 4-1 downsampler. GMSK and EDGE specific
    sections operate at 1 SPS.

commit af717b2d3c7fd9197edec715c3c0be70697c591a
Author: Tom Tsou <tom.tsou at ettus.com>
Date:   Sun Mar 6 22:19:15 2016 -0800

    EDGE: Add random burst generator filler option
    When EDGE is enabled with the '-e' option, the random burst generator
    switches from GMSK normal bursts to 8-PSK EDGE bursts.
      $ ./osmo-trx -e -r 7

commit 8ee2f38a87df07462467865cde16ab7e7508bd0e
Author: Tom Tsou <tom.tsou at ettus.com>
Date:   Sun Mar 6 20:57:34 2016 -0800

    sigproc: Add various GSM burst generators
    Setup generators for empty, random, and dummy bursts. This moves error
    prone burst length handling out of the Transceiver and into the signal
    processing core.

commit 4dfd64aa9e76af012b3cc0b6a73bbbcf3644d8e1
Author: Tom Tsou <tom.tsou at ettus.com>
Date:   Sun Mar 6 20:31:51 2016 -0800

    sigproc: Always use 625 sample length bursts with 4 SPS
    At 4 samples per symbol, we don't need to maintain the 156/157 sample
    slot structure to account for the GSM 156.25 sample burst length.
    Set the 4 SPS Laurent modulator to ignore the guard interval setting
    and always output 625 sample sized bursts. The EDGE 8-PSK modulator
    already has this behavior.

commit b0aefcbf47ed2eec1e4f3fd9bed72dde999913bf
Author: Tom Tsou <tom.tsou at ettus.com>
Date:   Sun Mar 6 03:44:34 2016 -0800

    EDGE: Add interfaces to enable EDGE transceiver
    Create EDGE slot type in the Transceiver. When EDGE mode is enabled
    for a particular slot, blind detection will be performed by
    correlating against EDGE followed by normal bursts if no EDGE burst
    is found.
