Florian Kaltenberger 76b55e9cbd Merge remote-tracking branch 'origin/develop-nr' into nr_fapi_for_push 2019-10-11 17:26:03 +02:00
Florian Kaltenberger 189e15aa80 improved real-time performance:
- gNB now only sends samples to USRP when DL slot. (should do the same for UE)
 - increased sf_ahead to 6
 - fixed timestamp for usrp_write at UE

Ahmed Hussein b28d006860 Minor Fixes in ulsim 2019-10-08 09:30:15 +02:00
Ahmed Hussein 3be72df335 Set start_rb to 0
- start_rb was set to 30, and nb_rb was set to 50 with NB_RB_DL = 106.
- When the DC subcarrier is included in the RB allocation,
  this causes errors in FFT/IFFT operations arounf the DC subcarrier
- This leads to errors in unscrambling and decoding

Ahmed Hussein 03ac9b03c8 TBS fix at UE side + minor restructuring in "phy_procedures_nrUE_TX"
- TBS calculation was performed 2 times. Once in "phy_procedures_nrUE_TX" and
  another in "nr_ue_ulsch_procedures". The TBS calculation was wrong in "phy_procedures_nrUE_TX"
  and correct in "nr_ue_ulsch_procedures".

- The data generation was performed in "phy_procedures_nrUE_TX" with a wrongly
  calculated TBS because "ulsch_ue->nb_re_dmrs" wasn't set to a value, so the calculated
  TBS would be more than it should be. This doesn't create a problem in the test because
  the comparison between the TX and RX data is made using the correctly calculated TBS
  which is smaller.

- Solution was to perform data generation in "nr_ue_ulsch_procedures", and remove TBS calculation
  in "phy_procedures_nrUE_TX"

Ahmed Hussein 3a8bf560da channel estimation, compensation, etc ..
Added the following folder:
- ../openair1/PHY/NR_ESTIMATION/

Added the following file to CMakelists.txt:
- ../openair1/PHY/NR_ESTIMATION/nr_ul_channel_estimation.c

Added the following functions:
- nr_pusch_dmrs_rx
- nr_gold_pusch
- nr_ulsch_channel_level
- nr_ulsch_channel_compensation
- nr_ulsch_scale_channel is commented out (I think only used for downlink)

Changes from Khalid Ahmed Mahmoud Mohamed:
- nr_pusch_channel_estimation is used
- nr_ulsch_scale_channel is used
- nr_ulsch_channel_level is used
- nr_ulsch_channel_compensation is used
- multiple logging options for channel and signal magnitude
