Abstract

This paper studies the performance of antenna diversity reception with selection combining (SC) and maximal ratio combining (MRC) in a correlated Rayleigh fading environment. Simple PDF expressions are derived for the output SNR of the SC and MRC diversity receivers. Based on the PDF, the average BERs for DPSK and NCFSK modulation are calculated to show the effects of the correlation. Moreover, the relationship between the average BER and the diversity antennas´ separation is given. The presented numerical results show that SC and MRC diversity reception can achieve a good performance only if the distance between two diversity antennas is larger than 0.3λ
