Error Performance Analysis of Multi-User Binary PAM TH UWB Systems with Multiple Receive Antennas

In this paper, multiple receive antennas are applied to multi-user binary pulse amplitude modulation (2PAM) time hopping (TH) ultra-wideband (UWB) systems to achieve high-data-rate communications. The effects of spatial diversity on the performance of 2PAM-TH-UWB systems are analytically investigated. We derive the expression for the received SINR after spatially combining and evaluate the bit error rate (BER) performance. Numerical results show that the BER performance can be enhanced by spatial diversity combining.
