Optimized Selection Diversity for Rayleigh Fading Channels

WebIn this paper, the impact of both maximal ratio combining (MRC) and relay selection on the physical layer security in wireless communication systems is investigated by analyzing critical issues such as the probability characteristics of the legitimate receiver (Bob) and malicious eavesdropper (Eve)'s end-to-end signal-to-noise ratio (SNR), the secrecy outage … Webrequires a C/N of 20 dB in Rayleigh fading but only 4 dB on a static channel [8]. We must first decide whether we are estimating the mean amplitude of the channel or the mean power. We will start with amplitude. In [2], Lee derives an expression for the mean amplitude of the Rayleigh fading channel assuming independent samples and using the central

The paper … Rayleigh fading is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices. Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also called a communication channel) will vary randomly, or fade, … See more Rayleigh fading is a reasonable model when there are many objects in the environment that scatter the radio signal before it arrives at the receiver.
