An Important Character for the Envelope Correlation Coefficient of MRC Signals over Correlated Rician Fading Channels

Envelope correlation coefficient (ECC) of the maximal ratio combining (MRC) output in correlated Rican fading channels is discussed in this paper in a close form, which is similar to that of single path conditions in stationary environment. Besides, with minor approximation we get the analytical formula outage probability. On this base, a simple relationship between ECC and the outage probability is derived, which indicates that ECC can be used to make predictions of outage probability.
