Abstract

The nonlinearity characteristic in satellite channel will causes spectrum regrowth and adjacent channel interference, which may have bad influence on communication system. In order to compensate for nonlinear distortion in satellite channel, combining with 16APSK, a digital baseband predistortion method based on Look-Up Table (LUT) is studied. Simulation results show that the method can improve the linearity of satellite channel and reduce spectrum regrowth, it can improve the bit error rate(BER) performance too.
