碩士 === 國立交通大學 === 電子工程系所 === 95 === This thesis considers the Orthogonal Frequency Division Multiplexing (OFDM) system’s undesirable feature of a large peak-to-average power ratio (PAPR) of the transmitted signal. In the MIMO-OFDM system, a low complexity structure to deal with PAPR problem is important because multiple transmitter. In the various PAPR reduction methods, the method selected mapping has high PAPR reduction capability but also high complexity and needs to transmit additional side information. In this thesis, we combine low complexity SLM structure and transmitting the side information, simulation display this method can reduce PAPR effectively. And implement to DSP board using 802.11n which is MIMO-OFDM system, profiling that this structure has low complexity and doesn’t engage much time in the system.
