摘要：
A new exact expression of BER (bit error rate) and user capacity performance for MC-CDMA (multi-carrier coded-division multiple-access) communication systems is proposed in this study. Different antenna configurations, including triangular and linear configuration antenna arrays, are applied. In addition, the branch is assumed to be operating in correlated Nakagami-m fading environments. The CF (characteristic function) is adopted to solve the PDF (probability density function) of the SNR (signal-to-noise ratio) at the MRC (maximal ratio combining) output instead of other complicated analytical methods. Finally, the numerical results obviously show that the performance degradation of the MC-CDMA system is sensitive to the correlation of fading channels, which is validated by comparing the results shown in certain published research [8].
