Abstract

Currently, although there exist only a few schemes that can reduce the peak-to-average power ratio (PAPR) of space-frequency block coded multi-input multi-output-orthogonal frequency-division multiplexing systems, they have much calculation complication and redundancy. This paper presents an optimized iterative (OPI) scheme to solve high PAPR. With this scheme, optimal sequence combinations are gotten on the basis of the value of PAPR. After that, the subblocks of the optimal sequence combinations are adjusted on a small scale so that we can obtain more satisfactory sequence combinations with multi-iteration to improve PAPR performance. Regarding calculation complication, the scheme only optimizes candidate sequences that improve PAPR performance, so as to significantly reduce the computation. Presetting the PAPR threshold for the system further reduces the computational complexity. Theoretical analysis and simulation results prove that OPI scheme proposed in this paper reduces not only the PAPR but also the computational complexity.
