摘要

提出了一种时域选择性映射技术，用于降低多输入多输出正交频分复用(OFDM)系统的峰均功率(PAPR)。候选的选择是从连续MIMO-OFDM块的各种组合中获得的。如果组合方式设计得当，不会降低误差性能。

A low-complexity selective mapping PAPR reduction scheme for coded MIMO-OFDM

We propose a time-domain selective mapping technique for reducing the peak-to-average power (PAPR) of the multi-input multi-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. The candidates for selection are obtained from various combinations of consecutive MIMO-OFDM blocks. The error performance will not be deteriorated if the way of combination is properly designed.
