Abstract
The paper researches the MSE (mean square error)criterion which combines the non-linearity of high power amplifier and the PAPR (peak to average power ratio)of OFDM (Ortho-gonal Frequency Division Multiplexing)signals to substitute PAPR criterion.The simulation results show that MSE criterion method can improve the system performance obviously,in multi-path channel condition,the system has 2dB better performance than PAPR criterion system.In good channel condition,SC-FDMA (single-carrier frequency division multiple access)system has 0.4dB better performance than OFDM system.The OFDM application for satellite can push for-ward the technique fusion of satellite communication and ground communication.关键词
