Abstract :
In this paper, we consider the error performance for downlink multicarrier code-division multiple access (MC-CDMA) system with space-time block codes (STBC) in correlated Rayleigh fading channels. An exact bit error rate (BER) is obtained for the system with maximal ratio combining (MRC) scheme based on the characteristic function (CF) and residue calculation method. Simulation results are also provided to verify our results.
