Abstract
The performance of error probability for TCM-8PSK with nonlinearity of high power amplifier was derived
firstly.Then
the dynamic simulation tool — Simulink included in Matlab was used to simulate and verify the derivation result.Finally
the equalization algorithm based on LMS was presented and at the same time the performance was simulated.The results of derivation and simulation are shown that the equalization algorithm reduces the effect of nonlinear distortion and keeps the gain of TCM-8PSK under the nonlinearity condition.
