A Study on the Wide-Sense Stationarity and Mean Ergodicity of SOC Rayleigh Fading Channel Simulators
نویسندگان
چکیده
Stationarity and ergodicity are desirable properties of any stochastic simulation model for small-scale mobile radio channels. These properties enable the channel simulator to accurately emulate the channel’s statistical properties in a single simulation run without requiring information on the time origin. In a previous paper, we analyzed the ergodicity with respect to (w.r.t.) the autocorrelation function (ACF) of seven fundamental classes of stochastic sum-of-cisoids (SOC) simulation models for mobile Rayleigh fading channels. In this paper, we continue our investigations on the subject by providing a comprehensive study on the wide-sense stationarity and the ergodicity w.r.t. the mean value of these classes of SOC channel simulators. The obtained results can be used in connection with those presented in our previous paper to design efficient channel simulators for the performance evaluation of modern mobile communication systems.

On the Autocorrelation Ergodic Properties of Sum-of-Cisoids Rayleigh Fading Channel Simulators
In this paper, we analyze the autocorrelation properties of seven fundamental classes of stochastic sum-of-cisoids (SOC) simulation models for narrowband mobile Rayleigh fading channels. The purpose of this analysis is to determine which classes of SOC models are autocorrelation ergodic (AE), i.e., for which classes of simulation models the time autocorrelation function (TACF) equals the autoco...

In this paper, we investigate the correlation and ergodic properties of the squared envelope of a class of autocorrelation-ergodic (AE) sum-of-cisoids (SOC) simulation models for mobile Rayleigh fading channels. Novel closed-form expressions are presented for both the ensemble and the time autocorrelation functions (ACFs) of the SOC simulation model’s squared envelope. These expressions have be...

– Channel simulators based on Rice’s sum-of-sinusoids are playing an important role in mobile fading channel modelling. However, the parameters of the sum-of-sinusoids have to be determined sophisticated to fully exploit the great potential that this powerful procedure has to offer. This paper provides a fundamental work on the stationary and ergodic properties of sum-of-sinusoids-based Rayleig...
متن کاملEnergy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels
In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
