文摘Presents a phase compensation against the signal distortion mainly caused by TWTA to solve the problem of compensation and modelling of a nonlinear QPSK satellite channel assumed to be bandlimited and exhibit both amplitude and phase nonlinearities, and to lower the bit error probability of nonlinear channel, and concludes with simulation results that the compensation against phase distortion of TWTA can significantly improve the nonlinear performance of the channel.
