Abstract
In this paper we present a new method for mitigating narrowband interference in multiband OFDM (MB-OFDM) ultra wideband (UWB) systems. The method employs spectral shaping of the transmitted signal using binary signature sequences with minimum total squared correlation (TSC) to avoid the narrowband interfering signal. We illustrate the proposed method with plots that show the spectrum of the transmitted signal with and without spectral shaping, and present also simulation results that show improvement in the bit error rate (BER) performance of the system when the method is applied.
