Abstract

The authors consider the estimation of symbol error rate (SER) for digital signals transmitted through a satellite channel with a memoryless bandpass nonlinearity, typically an on-board TWT (traveling-wavetube) amplifier in a satellite repeater, when the noise at the input of a nonlinear element is nonnegligible. An improved method of importance sampling is used for SER estimation in a simulation model of a nonlinear satellite channel. The characteristics of the simulation model are as follows: the modulation can generate an MPSK or MQAM signal; at the inputs of the transponder and the receiver Butterworth or Gauss filters are used; the receiver utilizes a device for optimum phase shift of the carrier; and signal sampling is performed at the optimal moment during the signaling period. This model is also used for the analysis of the influence of other system parameters (e.g. filter type, kind of modulation, and backoff) on the quality of signal transmission. Simulation results are presented.<>

有效重要抽样方法在数字卫星链路仿真中的应用

本文研究了当非线性元件输入处的噪声不可忽略时，通过无记忆带通非线性卫星信道传输的数字信号的符号误码率估计问题。针对一个非线性卫星信道仿真模型，提出了一种改进的重要采样方法来估计卫星信道的SER。仿真模型的特点是:调制可以产生MPSK或MQAM信号;在应答器和接收机的输入端使用巴特沃斯或高斯滤波器;接收机利用用于载波的最佳相移的装置;在信令周期的最优时刻进行信号采样。该模型还可用于分析其他系统参数(如滤波器类型、调制方式、退离)对信号传输质量的影响。给出了仿真结果。
