Abstract

The paper presents the average bit error rate (BER) of a maximal ratio combining (MRC) two-dimensional (2D)-RAKE receiver in correlated frequency selective Nakagami fading environments in the presence of multiple co-channel interferences. A closed-form expression of the simple approximated probability density function for the signal-to-interference-plus-noise ratio (SINR) is derived for the receiver with multiple correlated antennas and multiple RAKE branches in arbitrary fading environments. The effects of spatial and temporal diversity order, angular spread, antenna spacing, average multi-path strength and fading severity on the performance of the MRC 2D-RAKE receivers are all illustrated.
