Abstract

In this paper we investigate the effect of timingjitter on the bit-error-rate (BER) performance of correlator receivers with maximal-ratio-combining (MRC) receive diversity in the IEEE 802.15.6a on-body-to-off-body WBAN channel on the ultra wideband (UWB) range. In particular, we study the performance of optimal and low-power rectangular templatebased receiver alternatives assuming equally probable pulse position modulation (EC-PPM) scheme. Numerical results show that rectangular-templates are traded for 0.4 dB and 0.2 dB bit-energy-to-noise ratio degradation for timing-jitter equal to 0 psec and 10 psec, respectively at BER = 1e-2. On the other hand, at timing-jitter of 20 psec, they achieve approaching performance to optimal template-based detectors. Also, results show that timing-jitter equal to 10 psec and 20 psec cause 1.5 dB and 3 dB bit-energy-to-noise ratio performance degradation for the same BER as compared to the no-timing-jitter case for both optimal and rectangular template-based receivers.
