The Effect of Narrowband and Wideband Interference on the BER of MB-OFDM UWB Links

This work is an exploration of the impact of interferers on an ultrawideband (UWB) transmitterreceiver link. Both narrowband and wideband (specifically, UWB) interference is considered. Two physical layer models are built and simulated. The performance metric is the link’s bit error rate (BER). For both the narrowband and UWB interferer models, the dependence of the BER on the power of the interferer is presented. For the narrowband interferer case, the impact of the relative placement of the signal within the UWB link’s spectrum is simulated and discussed. Similarly for the UWB interferer, the time-frequency code (TFC) is varied to quantify the effect of spectrum overlap between co-located UWB networks on BER.
