Sensitivity analysis of compact antenna arrays in correlated Nakagami fading channels

This paper presents the average error probability performance of a compact space diversity receiver for the reception of coherent binary PSK signals through a correlated Nakagami (1960) fading channel. Analytical expression of the average BER is derived as a function of the covariance matrix of the multipath component signals at the antenna elements. The sensitivity of the performance to the operating environment (fading, angular spread, mean angle-of-arrival and input branch SNR) and the antenna array configuration (diversity order, antenna separation and electromagnetic coupling) is investigated
