It is difficult to analyze the performance of OFDM-CDMA systems. To accomplish this task, we need to characterize the correlation matrix among spreading sequences, because the system performance dependent on the choices of signature sequences. Although the performance is not sensitive to the choices of spreading sequences when long random spreading codes are employed , it is still mathematically demanding to evaluate the performance by large random matrix theory. OFDM-IDMA does not involvefatcat:fepcoe2dz5g3vcdvverqejzdfq
