Abstract :
In order to accurately quantify the degree of fading envelope correlation among the received signals at the antenna elements of an adaptive array operating in a frequency-selective environment, this paper builds on a simple analytical model to yield novel closed-form, finite-sum expressions for the covariance and correlation coefficients as a function of spatial and frequency separation.
