Abstract :
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 point from the system simulation.
