摘要：
This paper investigates the application of spatial shifting (SS) of partial transmit sequences (PTSs) in multiple-input multiple-output OFDM. The technique rearranges the transmit (TX) vector in such a way that subparts are transmitted on those TX branches that result in the lowest overall peak-to-average power ratio. The application of different subcarrier grouping schemes and the combination of SS with phase shifting (PS) of the PTSs is investigated. Furthermore, a transparant extension of the techniques, without extra signalling overhead, is proposed. Numerical results prove the effectiveness of the SS and the combined SS/PS approach.
