METHOD AND APPARATUS FOR REDUCING PEAK-TO-AVERAGE POWER RATIO (PAPR) OF ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) SIGNAL AND TRANSMITTER

摘要

Methods and apparatus for reducing a peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal in an MIMO-OFDM communication system is provided, in which the method for reducing the PAPR of the OFDM signal may identify interference generated in an MIMO communication system, and adjust a clipping ratio (CR) for an effect of a clipping distortion to be less than an effect of interference.
