PRS based Channel estimation at OAI nrUE
Time of arrival(ToA) estimation at nrUE based on channel impulse response(time domain)
Finer ToA estimation by 16x oversampled IDFT for channel impulse response
T tracer dumps for PRS channel estimates
FR1, FR2 gNB and UE configs for PRS testing
Multiple gNB scenario validated with gNBs synced via GPSDO
In FR1 and FR2 modes, PRS signal is successfully decoded on Spectrum Analyser R&S Rel16 version
