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 this paper, a low complexity peak-to-average power ratio (PAPR) reduction scheme is proposed for OFDM systems. By utilizing the properties of Discrete Fourier Transform (DFT), the proposed scheme divides the OFDM symbol into two disjoint subblocks in time domain, and generates a set of candidate signals by cyclically shifting one of the subblocks and sums them up. From the candidate signals, the...
