Rayleigh signal fading due to multipath propagation in wireless channels is widely modeled using sum-of-sinusoids simulators. In particular, Jakes’ simulator and derivatives of Jakes’ simulator have gained widespread acceptance. Despite this, few in-depth studies of the simulators’ statistical behaviors have been reported in the literature. Here, the extent to which Jakes’ simulator adequately ...

We calculate the capacity of a multiple-antenna wireless link with M -transmit and N -receive antennas in a Rician fading channel. We consider the standard Rician fading channel where the channel coefficients are modeled as independent circular Gaussian random variables with non-zero means (non-zero specular component). The channel coefficients of this model are constant over a block of T symbo...

Abstract— This paper addresses the design and performance evaluation with respect to capacity of M-PSK turbo-coded systems operating in frequency-flat, time-selective Rayleigh fading. The receiver jointly performs channel estimation and turbo decoding, allowing the two processes to benefit from each other. To this end, we introduce a suitable Markov model with a finite number of states, designe...

In this paper addresses Rayleigh fading networks, and in particular, wireless ad-hoc and sensor networks over Rayleigh fading channels. First, we will model Rayleigh fading networks and show how to map the wireless fading channel to the upper layer parameters for cross-layer design. Based on the developed fading network model, we will consider two scarce resources of wireless networks, namely e...

In this paper, we study the ability of transmit diversity to provide diversity benefit to a receiver in a Rayleigh fading environment. With transmit diversity, multiple antennas transmit delayed versions of a signal to create frequency-selective fading at a single antenna at the receiver, which uses equalization to obtain diversity gain against fading. We use Monte Carlo simulation to study tra...

In this paper the receiver for the demodulation of M-FSK signals in the presence of Gaussian noise, intersymbol interference, impulse interference and fading is considered. The probability density function of M-ary FSK signal in the presence of noise, interference and fading is derived. These interferences can seriously degrade the communication system performances. Key-Words: M-ary Frequency S...

The major Objective of simulating the radio propagation channels is to substantiate the design and performance of wireless communication systems. In the early stage of analysis and performance of wireless transceiver design fading channel simulators plays a vital role. The software simulators are painless to design, where as various hardware simulators have been proved that they offer distinct ...
