MIMO-OFDM system inherits high peak-to-average power ratio (PAPR) from OFDM. This paper presents a partial shift mapping (PSM) combining with inter-antenna switch (IAS) for MIMO-OFDM systems with low complexity. By utilizing the properties of OFDM signal, the time domain signal of disjoint subblocks are obtained by only one IFFT per antenna and the signals are cyclically shifted to get candidate signals in PSM. And the IAS is adopted to exchange these signals of disjoint subblocks between the antennas to improve the PAPR performance. Based on the analyses and simulations, it is shown that the performance of PSM is comparable to that of SLM, and combining with IAS it outperforms SLM about 1dB with lower complexity. © 2013 IEEE. |
