to get SRS signal iq data
I try to print the SRS signal's real and imaginary parts using the debugging part of nr_ul_channel_estimation.c.
#ifdef SRS_DEBUG
int subcarrier_log = subcarrier-subcarrier_offset;
if(subcarrier_log < 0) {
subcarrier_log = subcarrier_log + frame_parms->ofdm_symbol_size;
}
if(subcarrier_log%12 == 0) {
LOG_I(NR_PHY,"------------------------------------ %d ------------------------------------\n", subcarrier_log/12);
LOG_I(NR_PHY,"\t __genRe________genIm__|____rxRe_________rxIm__|____lsRe________lsIm_\n");
}
LOG_I(NR_PHY,"(%4i) %6i\t%6i | %6i\t%6i | %6i\t%6i\n",
subcarrier_log,
((c16_t*)srs_generated_signal[p_index])[subcarrier].r, ((c16_t*)srs_generated_signal[p_index])[subcarrier].i,
((c16_t*)srs_received_signal[ant])[subcarrier].r, ((c16_t*)srs_received_signal[ant])[subcarrier].i,
ls_estimated[0], ls_estimated[1]);
#endif
But the results had bad correlation with the SRS iq data from other software like matlab nr tool.
is there any further process need to be done on srs_received_signal, or it has been processed and it already not a pure siganl iq data or i should look up to some other script?
