Envelope Correlation of Wide-band Signals in Rayleigh Fading and its Implications for Frequency Diversity
نویسندگان
چکیده
In this paper, we analyze the envelope correlation of two resolvable paths belonging to replicas of a wide band signal1 modulated on two subcarriers in a Rayleigh fading channel. The results indicate that the frequency correlation of resolvable paths not only depends on the rms delay spread but also on the signal bandwidth. The results can be used in appropriately choosing the subcarriers of communication systems employing frequency diversity for wide band signals.

Energy 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...
متن کاملStatistical modeling of the indoor radio channel at 10 GHz through propagation measurements .I. Narrow-band measurements and modeling
The aim of this paper is to report the results of a propagation measurement experiment to reach a statistical model of the indoor radio channel at 10 GHz using directive antennas at both terminals. The measurements were conducted on a floor of a university building. The distribution of the received fading envelope was tested to fit the Rayleigh and Rician distributions, but were not satisfactor...
متن کاملDetection of frequency modulated signals in Rayleigh fading channels based on time-frequency distributions
One of the applications with nonlinear nonstationary signals lies in mobile communications where nonlinear information bearing signals are faded by the time-varying propagation medium. Consequently, the envelope of the received signal is often modelled by a Rayleigh distribution. This Rayleigh fading severely degrades the performance of the mobile radio transmission system. Diversity reception ...

متن کاملA Blind Hammerstein Diversity Combining Technique for Flat Fading Channels
Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...
