| Abstract(in English) | The authors have proposed a peak amplitude cancellation scheme for peak-to-average power ratio (PAPR) reduction in multi-input multi-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. The peak amplitude of OFDM signal is iteratively suppressed by adding an OFDM peak cancellation (PC) signal with co-phase subcarriers in a particular time instance. In the proposed scheme, the PC signal is iteratively added to the transmit signal so as to reduce the maximum amplitude to a given threshold level, while both adjacent channel leakage power ratio (ACLR) and error vector magnitude (EVM) are restricted below acceptable levels. We evaluates PAPR reduction and BER performance of MIMO QAM-OFDM systems using the proposed method under various scenarios. Our simulation results clarified that normalized instantaneous power of transmit signal can be reduced by 2.7dB compared to case without PAPR reduction under requirements of ACLR ≦ -50dB and EVM ≦ -30dB, in 2 x 2 MIMO-64QAM-OFDM system using the proposed method. |
