罗兰C接收机中噪声的抑制技术

Noise Suppression Technique in Loran-C Receivers

讨论了对罗兰C脉冲累加和平均抑制噪声的原理。用Remez交换算法设计优化的FIR数字滤波器并应用于罗兰C信号处理中,然后结合这两种方法,进行去噪仿真。

This paper discusses the principle of noise suppression technique by accumulating and averaging the loran-C pulses. The FIR digital filter designed with Remez exchange algorithm is applied in the processing of loran-C signal. Then, it combines with two methods and filters the processed loran-C signal by the FIR filter. According to simulation, the result of the method to suppress noise in loran-C is fine.
