OFDM PAPR METHOD AND APPARATUS FOR REDUCING PEAK-TO-AVERAGE POWER RATIO OF OFDM SIGNAL AND TRANSMITTER

摘要

Disclosed is a PAPR reduction method and apparatus for reducing PAPR of an OFDM signal in a MIMO-OFDM communication system. The PAPR reduction method of an OFDM signal according to an embodiment may identify interference occurring in a MIMO communication system, and adjust a clipping ratio so that the effect of distortion caused by clipping is less than the effect of interference.
