In this study, we have proposed a partition dummy sequence insertion (PDSI) method to reduce the high peak-to-average power ratio (PAPR) problem for the Orthogonal Frequency Division Multiplexing (OFDM) signal in the 802.11a WLAN with space-time block coding (STBC) system. The results show that the proposed STBC-PDSI method can avoid the BER degradation for different nonlinearity and the saturation...
OFDM (Orthogonal Frequency Division Multiplexing) technique has been widely adopted in many wireless communication systems due to its high data-rate transmission ability and robustness to the multipath fading channel. One major drawback of the OFDM signal is the high peak-to-average power ratio (PAPR) problem. The high PAPR results in the in-band distortion and out-of-band radiation when the OFDM...
