Abstract :
In this paper, taking the channel estimation error (CEE) and noise into consideration, an analytical expression for envelope correlation coefficient (ECC) of the maximal ratio combining (MRC) output has been obtained in correlated Rician fading environments in the high signal-to-noise ratio (SNR) region, which provides a deep insight into the impacts of CEE, noise, frequency separation, Rician factor and channel attenuation, etc. Besides, we found that the ECC can be used to predict system performance such as average channel capacity and outage probability quantitatively in the identical statistical characteristic environment.
