Abstract

Increased channel capacity and enhanced BER performance are two benefits of integrating MIMO and OFDM methods in a MIMO-OFDM wireless communication system. Because of this, the method for high data-rate transmission is now very compatible with both present and next generations of communication systems. Nevertheless, the method also bears the significant PAPR issue related to OFDM signals, which still needs a workable solution. An technique for reducing PAPR is presented in this study to address the issue of excessive PAPR in MIMO-OFDM systems. The suggested technique combines the original transmit signal with a created peak-cancelling signal using a low-complexity signal mixing idea. The suggested method's computational complexity,
