Throughput of optimal and suboptimal low-power IR-UWB coherent receivers for wireless body-area-networks (WBANs)

Abstract

Impulse radio ultra wide band (IR-UWB) systems have the potential for low-power consumption as well as high data-rates over short distances. This makes them an attractive candidate for emerging wireless body-area-network (BAN) applications. In this paper, we investigate the performance of low-power suboptimal real sinusoidal-template based detectors for M-ary pulse-amplitude-modulation (PAM) and M-ary equally-correlated pulse-position-modulation M-ary (EC-PPM) modulation techniques in multipath channels. Furthermore, we provide numerical results in the UWB-based IEEE 802.15.6a channels, and evaluate the corresponding attainable throughput.
