Abstract :
A new method to reduce the MIMO-OFDM peak-to-average power ratio (PAPR) is proposed. This method applies time and spatial two-dimensional subblock permutation to the multiple antenna OFDM system based on a timeslot structure. The PAPR of multiple OFDM symbols can be significantly decreased at the same time with limited complexity
