Linear Estimation of Signals Transmitted over the IEEE 802.15.3a UWB Channel
نویسندگان
چکیده
When transmitting a known signal over a multipath channel, the received waveform is a stochastic process due to the random nature of the multipath arrival times and gains. Any program aimed at linear estimation of the random waveform requires its correlation function. Explicit formulas are given for this correlation function when the multipath arrival times and gains are described by the recently developed IEEE 802.15.3a ultra-wideband (UWB) channel model. When the transmitted signal is a Gaussian monocycle, the correlation function can be obtained in closed form. More generally, structural properties of the correlation function are derived, and it is shown that linear estimation of UWB quantities is tractable.

In this paper, a Medium Access Control (MAC) protocol is proposed to investigate Quality of Service (QoS) for multimedia traffic transmitted over Ultra Wide-Band (UWB) networks and increase the system capacity. This enhancement comes from using Wise Algorithm for Link Admission Control (WALAC) which has three suggested versions. The QoS of multimedia transmission is determined in terms of avera...

In this paper, Ultra-wideband (UWB) multiple access relay channel with correlated noises at the relay and receiver is investigated. We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate some results numerically and show that noise correlation coefficients play important role in determining relay position.

Closed-form expressions for the average signal-tonoise ratio (SNR) and amount of fading are derived for a rake receiver using maximal-ratio combining on the IEEE 802.15.3a ultra-wideband (UWB) channel model. It is also shown that all moments of the SNR and all joint moments of the channel coefficients can be expressed in closed form.
