osmo-bts.git branch ttsou/egprs created. 0.4.0-209-g7a19ec2

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 "Osmocom BTS-side code (Abis, scheduling, ...)". The branch, ttsou/egprs has been created at 7a19ec22c5700f578fef9d583e18e90eff03b160 (commit) - Log ----------------------------------------------------------------- http://cgit.osmocom.org/osmo-bts/commit/?id=7a19ec22c5700f578fef9d583e18e90… commit 7a19ec22c5700f578fef9d583e18e90eff03b160 Author: Tom Tsou <tom.tsou(a)ettus.com> Date: Fri Jul 1 00:10:31 2016 -0700 trx: Enable EGPRS handling through burst lengths Existing interfaces are coded with the implicit expectation of using a burst sequence length of 148, which is constant with GSM and GPRS. That changes with EGPRS, where the burst length may be 444 due to the use of 8-PSK instead of GMSK modulation. Setup the interface to accept and return a length value with the burst sequence. This allows 444 length bit vectors to/from the EGPRS decoder/encoder. Length is explicitly used as a identifier for 8-PSK vs. GMSK modulated sequences.

Includes Type 1, 2, and 3 headers and tables from 3GPP TS 44.060 in order to independently recover coding and puncturing scheme (CPS) parameters for each coded message.
