Performance Comparison between CI/OFDM and OFDM Systems

摘要：

Carrier Interferometry Orthogonal frequency division multiplexing (CI/OFDM) has gained a great deal of attention recently because of its good bit error rate (BER) and low peak-to-average power ratio (PAPR) performance. In this paper, we investigate the performance of CI/OFDM based on a new implementation model for both zero forcing (ZF) and minimum mean square error (MMSE) equalization. We further provide an analytical comparison between CI/OFDM and traditional OFDM. According to our analysis, the BER and PAPR advantage of CI/OFDM over the traditional OFDM are at the cost of low capacity. Moreover, we argue that the more frequently the channel deep fades occur, the more significant the advantage of CI/OFDM over OFDM is. The simulation results validate the theoretical analysis.
