One of the major concerns in the MIMO-OFDM system is the high peak-to-average power ratio (PAPR). In this article, a combinational scheme, active partial sequence (APS), is proposed to combat PAPR in MIMO-OFDM under Rayleigh fading environment. The key idea of the APS method is to combine the approximate gradient project followed by partial transmit sequence technique. The simulation results show that the proposed method achieves a significant reduction in PAPR and maintains the same data rate without sacrificing the BER performance over other conventional techniques.
