EGPRS support MCS1 to MCS9 in UL and DLssharan/egprs
This release contains our EGPRS development done from December 2015 till February 2016. It includes rebase from Jan 2016 Master branch of Git but not the latest master available on date 22nd Feb 2016. The code has been Unit tested. It has not been tested in any integration environment. For details on the feature changes please refer the README.

The PCU is part of BSS, so it connects directly to SGSN.
+This release contains our EGPRS development done from December 2015 till February 2016. Please note that rebase from Master branch of Git was done on January 2016 so Latest submission on Master date 22nd February is not in our code base.
+
+Main features added with important files where modification were done.
+
+1) EGPRS MCS1 to MCS9 both in UL and DL.
+ rlc.h, rlc.cpp, tbf_dl.cpp, tbf_ul.cpp.
+2) RLC retransmission, re-segmentation and split block support for both UL and DL.
+ rlc.cpp, tbf_ul.cpp, tbf_dl.cpp.
+3) Selection of appropriate CPS for retransmission including padding of 6 octets case.
+ gprs_coding_scheme.cpp.
+4) For encoding/decoding of compressed rbb in EGPRS ack/nack, implemented algorithm based on code word trees.
+ encoding.cpp, rlc.cpp.
+5) Fix for length of descriptor in EPDAN bitmap.
+ gsm_rlcmac.h, gsm_rlcmac.cpp, bts.cpp.
+6) Transmission/Reception of data flow for MCS1 to MCS9.
+ tbf_dl.cpp, tbf_ul.cpp, decoding.cpp.
+7) Fix for encoding of padding bits.
+ csn1.cpp
+8) Unit testing of the above implementation.
+ EdgeTest.cpp.
