N2 - To alleviate the high peak-to-average power ratio (PAPR) and sensitivity to carrier frequency offset (CFO) problems, an asymmetric OFDM (A-OFDM) system has been recently proposed. 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.
