英文摘要
In MIMO systems, it is important to reduce peak-to-average power ratio (PAPR) of the transmit signal for improving power efficiency at transmitter power amplifier. The objective of this research is to develop adaptive signal processing techniques for power efficient MIMO multi-carrier/multi-code communication systems. Phase control based PAPR reduction techniques and adaptive peak amplitude cancellation techniques for MIMO multi-carrier and vector coding systems are developed. The effectiveness of the developed PAPR reduction methods combined with an adaptive linearization techniquewas confirmed.
