In this paper, we have proposed a new PAPR reduction technique in MIMO-OFDM systems. It achieves the result which proves the PAPR of 2×2 MIMO-OFDM systems. The parameters of the simulation are determined by standard IEEE 802.11n. From the simulation results, it is shown the proposed method has better PAPR performance in this system. Additionally, when the number of sub-blocks is increased, high PAPR reduction performance can be obtained.
