Hi Piotr, I was facing the same issue, and the issue is caused by Schmidl-Cox sometimes detecting the packet boundaries a little late. This cannot really be helped, as channel noise may force the correlator to detect a peak/plateau later than it … WebAn OFDM communication link is implemented using the software tool GNU Radio and the NI USRP B210 radio card. Each card is connected via USB to a PC running either a OFDM transmitter or receiver. The USRP is a platform for implementation of SDRs and is equipped with DACs, ADCs, MIMO antennas, reference clocks and RF chip transceivers. …
