“…A different approach is proposed in [16] to analyse the influence of channel and system parameters : by computing the first and second order moments of the received UWB pulses, the authors can express the intra-burst interference resulting from multipath propagation. In [17], the authors derive a few analytical expressions for IFI/ISI in pulsed direct sequence (DS) and hybrid DS/TH UWB communications, considering a frequency selective Nakagami fading channel. With standard Gaussian approximation of ISI/IFI, an expression of the error probability is given for a MRC rake combiner and the effects of various system parameters on the performances are studied.…”

International audienceIn this paper, we develop a statistical characterization of the multipath interference in an Impulse Radio (IR)-UWB system, considering the standardized IEEE 802.15.4a channel model. In such systems, the chip length has to be carefully tuned as all the propagation paths located beyond this limit can cause interframe/intersymbol interferences (IFI/ISI). Our approach aims at computing the probability density function (PDF) of the power of all multipath components with delays larger than the chip time, so as to prevent such interferences. Exact analytical expressions are derived first for the probability that the chip length falls into a particular cluster of the multipath propagation model and for the statistics of the number of paths spread over several contiguous clusters. A power delay profile (PDP) approximation is then used to evaluate the total interference power as the problem appears to be mathematically intractable. Using the proposed closed-form expressions, and assuming minimal prior information on the channel state, a rapid update of the chip time value is enabled so as to control the signal to interference plus noise ratio

This paper presents the performance evaluation of a common signal employed to enable coexistence between heterogeneous physical (PHY) layer designs in the Smart Utility Networks (SUNs). The coexistence mechanism, known as Multi-PHY Management (MPM) uses a common PHY signaling specification known as the Common Signaling Mode (CSM) to facilitate interference avoidance/mitigation among the three specified alternative PHYs in the on-going industrial standardization for SUN, namely the IEEE 802.15.4g. The CSM is a signaling design commonly supported by all three PHYs in the 802.15.4g. In this paper, we have analyzed the performance of the CSM from the perspectives of receiver type, likelihood of detection and achievable range. The effectiveness of CSM is an essential factor for the performance of MPM. It is found that by using a correlator receiver, the likelihood of detecting the CSM is typically 20-25dB better than an energy detection receiver. The achievable transmission range of the CSM is 90m with a correlator receiver and is decreased to 30m with an energy detector.

“…In [5] the authors outlined some attractive features of TH-SS (time hopping spread-spectrum) multiple-access system and estimated the multiple-access capability for both analog and digital data modulation schemes under ideal channels. In [6] a frequency selective Nakagami fading channel was considered to analyze inter-symbol/frame interference for pulsed DS (direct sequence) and hybrid DS-TH (DS-time hopping) UWB communications. In [7] the channel models for UWB were overviewed for UWB propagation channels.…”

The evaluation of System Performance of UWB (ultra-wide band) jointing in MC (multi-carrier) signaling in correlated environments is presented in the report. The correlated Nakagami-m statistical distribution for the multipath fading model is assumed in this scenario. In fact to establish the model for analyzing in this article is using MC-CDMA (multi-carrier code-division multiple-access) system characterization combined with a UWB scheme. The average BER (bit error rate) is calculated and compared to a special case of previously published results. Studied results from this paper can be implied to approve the system performance for a UWB system combined with a MC-CDMA wireless communication system. It is worth noting that the Nakagami-m distributed fading parameter significantly dominates UWB system performance when it cooperates with MC signaling under a fading environment. Finally, it is worthy of noting that when the SNR (signal-to-noise ratio) at system’s receiver reaches a preset high threshold value, the parameter of power decay ratio effect could be not included.
