| 摘 要： | 多输入多输出正交频分复用（MIMO-OFDM）系统的高峰均功率比（PAPR）问题已经成为限制MIMO-OFDM技术应用和发展的主要障碍.针对这种情况提出一种由子块逐次取反（SSI）和循环限幅算法的联合方案,与连续次最优交叉天线旋转取反算法（SS-CARI）相比传输的边带信息更少,克服了概率类算法只能在概率上降低PAPR的缺陷和限幅算法带来的峰值再增长问题.仿真结果表明,此方案可有效抑制峰均功率比,同时不会产生过大的噪声.

| Abstract: | The problem of high peak-to-average power ratio(PAPR) becomes the main obstruction to apply and develop MIMO-OFDM systems.For this reason a new method combining the subblock successive inversion(SSI) with circle-clipping is proposed.Comparing with the subblock successive cross-antenna rotation and inversion(SS-CARI) it has less side information and overcomes the shortcoming that the probabilistic algorithm can only reduce PAPR in aspect of probability and the problem of peak re-growth which is brought by cl... |
