Abstract :
We propose a time-domain selective mapping technique for reducing the peak-to-average power (PAPR) of the multi-input multi-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. The candidates for selection are obtained from various combinations of consecutive MIMO-OFDM blocks. The error performance will not be deteriorated if the way of combination is properly designed.
