遥控副载波信号与高斯白噪声发生器设计研究

摘要

遥控副载波与高斯白噪声发生器是测控系统检测设备的重要组成部分,主要实现BPSK信号调制和高斯白噪声生成功能.该发生器通过在信号传输过程中加入随机噪声来模拟实际信号传输过程,通过在信号调制过程引入比例因子实现有效信号与高斯白噪声信号输出功率的可调,从而实现信噪比控制的目的.并应用于工程实践,证明了设计的有效性.%The controllable route sub-carrier and white Gaussian noise signal generator is an important part of TT&C (Tracking Telemetry and Command) system, which realizes BPSK signal modulation function and Gaussian niose generation function. In order to simulate the practical transmission process of signal, the generator adds random noise into the process of signal transmission. The generator also introduces proportion factor in the process of signal modulation to adjust the output power of signal and Gaussian noise. This generator is already applied to engineering practice, which indicates the validity of the presented method.
