Statistical analysis of interference effect from low data rate UWB signal on OFDM / Mohd Amin Mansor

This paper reports on the study of the interference effects from 2 types of ultra wideband (UWB) radar signals on a OFDM transmission system by simulation. The culprit UWB sources were: Gaussian monocycle pulse and UWB chirp signal. Average bit error rate (BER) degradation of the victim system was evaluated under in-band interference from the UWB signal. Simulation results show that both Gaussian monocycle pulse and UWB chirp signal waveform yield different BER characteristic compared to an AWGN. The Gaussian monocycle pulse resulted as the worse case where significant BER floor were observed at the victim receiver.
