In this paper, the theoretical bit error rate (BER) analysis of the A-OFDM systems is presented. Various modulation methods, i.e., BPSK and M-ray QAM, and equalization techniques, i.e., zero forcing (ZF) and minimum mean square error (MMSE) criteria are considered. Our analysis shows that the BER performance of the A-OFDM system bridges that of conventional OFDM and single carrier systems. Certain advanced equalizers, such as MMSE equalizer, are found to significantly improve the BER performance of the A-OFDM systems. The analysis approach is generally applicable to most modulation schemes and can be extended to any precoded OFDM systems.6en200810.1109/GLOCOM.2008.ECP.87467249160304
