Francisco 0ae304a6ed update sched rand tester to detect when tbs coderate exceeds 0.93 2020-12-12 15:59:27 +01:00
Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC 
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib

Francisco 8d181ef41c Optimization of cc_sched_ue::cqi_to_tbs(...) method via the use of root-finding algorithm 2020-12-12 15:59:25 +01:00
Francisco 94efeab672 Optimization of sched_ue methods to derive required number of prbs to allocate to a rnti 
This optimization has been achieved by:
- implementation of "false position method" root-finding algorithm
- application of the false position method in cc_sched_ue::get_required_prb_dl/ul(...)

The number of iterations in the worst case scenario, reduced from 100 to 5 with
the proposed algorithm.
