摘要：
In this paper we investigate the efficiency of linearization for pre-distortion in 16, 32 and 64-QAM modulation with convolution coding, utilized TWTA power amplifier with 1dB back-off in Ka-band satellite link for DVB-RCS services. The effect of the linearizer on spectrum and BER for different modulation and coding in DVB-RCS link would be compared using Matlab simulink.
