Error probability performance for WCDMA systems with multiple transmit and receive antennas in correlated Nakagami fading channels

The bit-error-rate (BER) performance of a 2D-RAKE receiver, in combination with transmit diversity on the downlink of WCDMA system, is presented. The analyses assume correlated fading between receive antenna array elements, and arbitrary number of independent but nonidentical resolvable multipaths; combined by the RAKE receiver, in the general Nakagami-m (1960) fading channel framework. The impacts of the array configuration (e.g. the number of transmit antennas and receive antennas, the antenna element separation) and the operating environment parameters (such as fading severity, angular spread and path delay profile), on the overall space-path diversity gain can be directly evaluated.
