摘要：

An improved method based on cross-antenna rotation and inversion (CARI) is presented for MIMO-OFDM peak-to-average power ratio (PAPR) reduction. Firstly, an optimal scheme is proposed for PAPR reduction, by employing the degrees of freedom of multiple antennas. Then two sub-optimal schemes are proposed to reduce computational complexity by transforming the subblock successively and setting a threshold. Simulation results have shown that the proposed suboptimal scheme, termed adaptive subblock successive transform (ASST) slightly outperforms the successive suboptimal CARI (SS-CARI) scheme but with remarkably lower computational complexity.
