| Abstract: | The modeling and simulation on URE link of DRSS channel are conducted.The nonlinear characteristics of HPA in URE link of DRSS channel are described by means of Saleh model.The effect of the channel nonlinear characteristic on the performance of the communication systems is analyzed by simulating the nonlinear ISI characteristic,frequency characteristics,star maps and bit error characteristic of 8PSK,16PSK and 16QAM modulated signals passing through DRSS URE nonlinear channel. |
