Description

OsmoTRX is currently only correlating with one of the three RACH sync sequences indicated in TS 05.02 5.2.7. We need to define TS1+TS2 as well as correlated against thosee during RACH detection

 const BitVector GSM::gRACHSynchSequence("01001011011111111001100110101010001111000");
+const BitVector GSM::gRACHSynchSequenceTS1("01010100111110001000011000101111001001101");       /* EGPRS with 8PSK in uplink */
+const BitVector GSM::gRACHSynchSequenceTS2("11101111001001110101011000001101101110111");       /* EGPRS without 8PSK in uplink */
