چکیده
In this paper we proposed an analytical method which is used for 802.15.3a UWB channel to find out the effect of rake receiver finger with Maximal ratio combining (MRC) scheme. We used a mathematical model which is derived while considering the receiver is MRC rake receiver. In this receiver we assigned weights to rake receiver finger in such a way to maximize the signal to noise ratio (SNR). With the help of maximal ratio combining (MRC) mathematical model we try to evaluate the performance result with different rake receiver finger.

A set of physical layer specifications is provided for a single-band and a dual-band UWB system. Both systems fulfill the FCC regulations on UWB devices. Only the singleband system fulfills the physical layer requirements from IEEE 802.15.3a. The single-band system gives reliable communication, i.e., a 90th-percentile PER equal to 8% for 1024 payload bytes, at 110 Mbps with a transmitter–receiv...

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.
