In this paper, we consider composite multipath/shadowing fading channels characterized by Nakagami- m fading with inverse Gaussian shadowing, and Rice fading with inverse Gaussian shadowing. These channel models are very convenient for land mobile satellite systems and communications with low mobility or stationary users. From an analytical standpoint, one major advantage of these models is that they...
Statistical properties of the four IEEE ultra-wide bandwidth channel models are derived. In particular, the correlations and probability density functions for the gains and powers of different multipath components are calculated. It is shown that most multipath components are correlated, and that most multipath components donpsilat follow a lognormal distribution. These results are useful in evaluating...
We study the performance of the autocorrelation receiver (AcR) with the transmitted-reference (TR) signaling scheme in the multipath UWB channel, where the fading of each resolvable multipath component is characterized by: 1) Nakagami distribution; 2) arbitrary fading parameter; and 3) arbitrary average power. The analysis, compared to conventional Rake receivers, is complicated by the fact that the...
