Performances of CS-DCSK UWB Communication System in the Presence of Narrow Band Interferers

This paper evaluates the bit error rate (BER) performance of a code-shifted differential chaos shift keying (CS-DCSK) ultra-wide bandwidth (UWB) system over indoor communication channels under the impact of both single and multiple narrow band interference (NBI) signals. We analyze the BERs both in single NB interferer and multiple NB interferes. The analytic results and simulation results show that NBI signal has a noticeable impact on the performance of UWB systems which are independent of the carrier frequency.
