摘要
首先推导了TCM-8PSK信号在带限非线性卫星信道下的误码率性能。其次,运用Matlab中的动态仿真工具Simulink仿真验证了误码率性能推导的正确性并在Saleh非线性模型下分别寻找到QPSK及TCM-8PSK的最佳工作点。最后,提出了改善非线性失真的均衡算法并给出了仿真结果。推导及仿真结果表明,研究非线性条件下的调制编码问题是十分必要的。
The performance of error probability for TCM-8PSK over the band-limited nonlinear satellite channel was derived firstly, Then, the dynamic simulation tool -- Simulink included in Matlab was used to simulate and verify the derivation result and the optimal working point for QPSK and TCM-8PSK were found under the condition of Saleh nonlinear model, Finally, the equalization algorithm used to improve the effects of nonlinear distortion was presented and at the same time the performance was simulated, The results of derivation and simulation show that it is necessary to study of TCM-8PSK for nonlinear satellite channel.
