Summary:
In this letter, a simple peak-to-average power ratio (PAPR) reduction method using subband permutation is proposed for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. The proposed method is shown to have a 2-3 dB PAPR reduction gain for 2 transmit antennas, compared with the conventional MIMO-OFDM, and a low computational complexity at the transmitter and receiver.
