“…The channel models in [4]- [7] do not consider the cluster phenomenon and shadowing effect as in the IEEE 802.15.3a channel model and therefore are insufficient and unrealistic for performance analysis compared to our proposed method. Secondly, [8]- [13] investigated the performance of UWB systems based on more sophisticated UWB channels, such as the IEEE 802.15.3a model. In [8], the authors applied the techniques of counting integrals and shot noise to derive the computation BER formula in the IEEE 802.15.3a channel assuming the received waveform can be observed over a finite-length window.…”

Abstract-In this paper, we present a computable bit error rate (BER) expression for the binary signals in the IEEE 802.15.3a ultra-wideband (UWB) channel. In the literature, the impacts of the RAKE receiver's finger numbers and lognormal shadowing on the BER performance have not been reported yet. We propose a characteristic function (CF) based BER formula to overcome the convergence problem of the existing moment generating function (MGF) approach when the BER calculation takes account of the shadowing effect. Simulation results demonstrate that the proposed CF-based computable BER formula can accurately estimate the complete effects of the cluster and ray arrival processes, the lognormal fading as well as shadowing, and the finger numbers at RAKE receivers.Index Terms-Bit error rate (BER), IEEE 802.15.3a channel model, RAKE receiver, shadowing, ultra-wideband (UWB).

“…Another is caused by the interference between a pulse and its own multipaths, which is called intra-symbol interference (IASI). The available literatures in this area have already analyzed the system performance in the presence of narrowband interference, multiuser interference, and multipath interference [3][4][5][6][7][8]. Reference [3] and [4] mainly discussed multiuser interference and proposed the energy-detection receiver and non-linear filtering approach to mitigate such interference.…”

Abstract-Bit error rate (BER) performance of impulse radio Ultra-Wideband (UWB) systems in the presence of intrasymbol interference, inter-symbol interference, multiuser interference and addictive white Gaussian noise (AWGN) is presented in this paper. By analyzing the indoor office LOS channel model defined by IEEE 802.15.4a Task Group and deducing the variance for intra-symbol interference (IASI), inter-symbol interference (ISI) and multiuser interference (MUI), the system BER expression is obtained and verified by MATLAB simulations. Through comparing the simulation results with and without intra-symbol interference, the conclusion that intra-symbol interference cannot be neglected is drawn-moreover, such interference will significantly decrease performance of UWB based wireless sensor networks (WSN). Then, the BER performance of UWB systems in multiuser environment is also analyzed and analysis results show that multiuser interference will further worsen the transmission performance of UWB systems.

This paper presents an analysis of the performance of a baseband multiple-input single-output (MISO) time reversal ultra-wideband system (TR-UWB) incorporating a symbol spaced decision feedback equalizer (DFE). A semi-analytical performance analysis based on a Gaussian approach is considered, which matched well with simulation results, even for the DFE case. The channel model adopted is based on the IEEE 802.15.3a model, considering correlated shadowing across antenna elements. In order to provide a more realistic analysis, channel estimation errors are considered for the design of the TR filter. A guideline for the choice of equalizer length is provided. The results show that the system's performance improves with an increase in the number of transmit antennas and when a symbol spaced Part of this work was presented in the ISSSTA'08 conference. equalizer is used with a relatively small number of taps compared to the number of resolvable paths in the channel impulse response. Moreover, it is possible to conclude that due to the time reversal scheme, the error propagation in the DFE does not play a role in the system's performance.
