Thomas Schlichter 942037beb3 5G NR: move CIR peak to 0 
The rotation compensating the shifted OFDM position _before_ the channel estimation makes the CIR peak move back to 0.
We have to take this into account on gNB side when calculating the timing advance command, and on UE side in the time adjustment.

Sakthivel Velumani 1991c2f9cd Revert "HACK: cut PUSCH and PDSCH OFDM symbol after complete CP" 
This reverts commit 87b53883b2.
 2021-04-23 15:42:16 +02:00
Thomas Schlichter 87b53883b2 HACK: cut PUSCH and PDSCH OFDM symbol after complete CP 
Currently we cute the PUSCH and PDSCH OFDM symbols starting within the last 1/8th of the CP to avoid ISI.
This time shift leads to a rotation in frequency domain.
The current PRB based channel estimation does not compensate for the rotation _within_ a PRB, leading to bad performance.

This commit should _not_ make it into develop branch, it is just for testing!
Instead, we should do some compensating rotation before channel estimation.

Included command line option to select interpolation method
 2021-03-05 11:44:31 +01:00
Raymond Knopp d26d60300e added a PRB-based channel estimation. It averages the 4/6 DMRS LS channel estimates and uses a single value per PRB. Improves performance of high MCS 
PHY_VARS_NR_UE now has a flag fd_lin_interpolation which turns this on/off. By default it uses the "new" method.
