Abstract

This paper analyzes the spectral efficiency of the incremental amplify-and-forward (AF) opportunistic relaying (OR) with outdated channel state information (CSI) over Rayleigh fading channels. According to the definition of distribution function, we obtain the cumulative distribution function (CDF) of the actual combined signal-to-noise ratio (SNR) received at the destination. Based on this CDF, the closed-form expression of the average spectral efficiency is derived for the incremental AF OR with outdated CSI. Numerical results show that as the average SNR of the direct link is much less than the threshold SNR, the spectral efficiency is zero, and as the average SNR is near the threshold SNR, outdated CSI deteriorates the spectral efficiency, whereas, as the average SNR is much greater than the threshold SNR, the spectral efficiency is hardly affected by outdated CSI.
