Performance of CM-TR UWB communication system in the presence of a single narrow band interferer

Abstract

This paper evaluates the bit error rate (BER) performance of a code-multiplexed transmitted-reference (CM-TR) ultra-wide bandwidth (UWB) system over Nakagami-m fading channels under the impact of a single narrow band (NB) interferer. The BER performance of CM-TR UWB in the presence of a single NB interferer is analyzed using sampling expansion method. The analytic expression shows that the performance of CM-TR UWB is independent of carrier frequency of the NB interferer. Moreover, simulations and analytic results show that the CM-TR UWB has better BER performance than that of TR-UWB under same strength of NB interferer.
