Raymond Knopp 2dfe84a7e4 bugfixing for UL. Remaining problems: CCE allocations in subframe 5 lead to occasional illegal DCI allocations (affects UL DCI which is missed by UE). waveform compliance with CQI in ULSCH. 2016-04-10 23:25:58 +02:00

Rohit Gupta 66dde65f2e added a new check for illegal file permissions to mbmssim.c, to avoid a segfault if permissions are invalid. 2016-04-05 21:44:41 +02:00
Rohit Gupta ca5ff31f32 updates to eMBMS. mbmssim and UE channel estimation. will not affect current gitlab CI tests. 2016-04-05 16:37:32 +02:00
Raymond Knopp 68fb9ef07f modifications to eMBMS-related L1 processing. mbmssim now works again (performance to be checked for 10/20 MHz), but error rates decay as they should with SNR. 2016-04-04 16:29:06 -07:00

lukashov 291a7f1752 1. Changing precoder to minimize interference: testing simple channels. 
2. Fixing confusion between dl_ch_rho2_ext and dl_ch_rho_ext[harq_pid][round].

lukashov 4573c0b962 Changes for SIC-receiver: 
1. in dlsim.c: now we check for the receiver type and, if SIC,  proceed through encoding, modulation, LLR compuattion and decoding
of the decoded TB0.
2. Implementing routines for vector-vector multiplication and vector-vector subtraction
3. Adding some printouts for debuging purposes.
4. New functions: modulation_SIC, dlsch_qpsk_llr_SIC
5. In phy_scope.c: changing llr plotting: now for the length of coded_bits_per_cw.
