“…It was shown in [23] that timing errors cause significant performance degradation to the BER. The same degradation to the symbol error rate was observed in [24] when time jitter is present. The degradation to channel capacity was not considered in [24] but will be presented in our work.…”

“…This arises due to the effects of timing jitters, tracking errors and unstable clocks 3 with jitter of 10 ps reported by Rowe 4 , et al The relative mobility between transmitter and receiver adds to the asynchronisation problem. Immediate fallout of timing jitter is performance degradation of correlation receiver, resulting in reduction of signal-to-noise ratio (SNR) [5][6][7] . The effects of timing jitter on the bit error rate (BER) performance and data throughput for wireless body area network (WBAN) were compared for equally correlated-pulse position modulation (PPM) scheme in Nasr & Shaban 8 .…”

In short-range networks such as wireless personal area networks (WPAN), multiple user wireless connectivity for surveillance would require a wireless technology that supports multiple streams of high-speed data and consumes very little power. Ultra wideband (UWB) technology enables wireless connectivity across multiple devices (users) addressing the need for high-speed WPAN. Apart from having a distinct advantage of higher data rate over Bluetooth v4.0 (24 Mbps), the UWB technology is also found to be tolerant to frequency-selective multipath fading. In this paper authors discuss a time-hopping pulse shape modulation UWB signalling scheme for ad-hoc high bit rate wireless connectivity for defence applications. Authors analyse multiple access interference for both Gaussian channel and frequency selective multipath fading channel to compare the effects of timing jitter on two types of pulse shapes, namely modified Hermite pulse (MHP) and prolate spheroidal wave functions (PSWF). Authors make a comparative analysis of the system performance with respect to PSWF and MHP to ascertain robustness to timing jitter. In the process, authors introduced a new metric of decision factor in timing jitter analysis.

“…For the conventional TH-UWB systems with M-ary orthogonal PPM and N-ary biorthogonal PPM modulations, some relative studies have been reported in [16][17][18][19][20] and [2,21]. The Gaussian distribution assumption can be adopted to model the MAI statistics to derive some simple theoretical analyses for the binary PPM, M-ary orthogonal PPM and N-ary biorthogonal PPM signaling [2,[8][9][10]16].…”

In order to increase the capacity and diminish the multiple access interference (MAI) of an ultra-wideband (UWB) system, we propose a new time-hopping/direct-sequence (TH/DS) scheme using N-ary biorthogonal pulse position modulation (BPPM). In contrast with the conventional TH/DS systems employing fixed partition of the TH slots (Shen and Ueng, Proceedings of the IEEE VTC-Spring, 2010), the proposed TH/DS system can put the start location of the TH slot in any one of Q available pulse positions within the frame. In the proposed TH/DS system, the modulation level of BPPM can be increased and the multiple access capability can be improved without degrading the system performance. Compared with the existing TH-UWB system that employs the whole frame to carry out TH process (Shen et al. IEEE Trans. Veh. Technol. 59(2), 742-753, 2010), the proposed system has the merits of smooth power spectral density and low receiver complexity. In this article, we also derive the probability distribution of MAI for each correlator's output of the proposed TH/DS system based on the analytic characteristic function technique. In order to verify the correctness of the performance analyses and to demonstrate the effectiveness of the proposed TH/DS system, some simulation results are given in both the additive white Gaussian noise channel and the realistic UWB fading channels. From the simulation results, we find that the proposed TH/DS system outperforms the conventional TH/DS scheme.
