The VA is already being used by the ms side and is part of the original gsm design. It only works for gmsk, 4sps, and needs a bit of rx burst scaling and burst shifting. Change-Id: I9d7a4ff72e323832a94d885d5714fcde01ceeb3d
About OsmoTRX
OsmoTRX is a software-defined radio transceiver that implements the Layer 1 physical layer of a BTS comprising the following 3GPP specifications:
- TS 05.01 "Physical layer on the radio path"
- TS 05.02 "Multiplexing and Multiple Access on the Radio Path"
- TS 05.04 "Modulation"
- TS 05.10 "Radio subsystem synchronization"
OsmoTRX is originally based on the transceiver code from the OpenBTS project, but setup to operate independently with the purpose of using with non-OpenBTS software and projects, specifically within the Osmocom stack. Used together with OsmoBTS you can get a pretty standard GSM BTS with Abis interface as per the relevant 3GPP specifications.
