Abstract
This paper reports on the study of interference effects from 2 types of Ultra Wide Band (UWB) radar signals on an OFDM transmission system by simulation. The UWB signals 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 signals in AWGN channel. Simulation results indicated that Gaussian monocycle pulse degrades the BER characteristic of an OFDM system more severe than a UWB chirp signal, where significant BER floor were observed at the victim receiver. The amplitude probability distributions (APD) of interfering UWB envelope signal at the victim receiver were analyzed.
