Abstract

This paper evaluates the performance of time hopping (TH) pulse position modulation (PPM) and TH binary pulse amplitude modulation (BPAM) systems in the presence of multi-carrier interference. In particular, we derive closed-form bit error probability (BEP) expressions for binary coherent TH-PPM and TH-BPAM systems based on matched filter reception by approximating the multi-carrier interference as sum of tone interferers and considering different scenarios such as AWGN as well as frequency-selective channels. Simulation results proves that the assumption of sum of tone interferers is a good approximation for an OFDM interferer and our analytical results show that the frequency selectivity of the channel of the interferer plays an important role on the performance.
