摘要
舰船通信系统的信号传输过程中受海上气象条件、干扰噪声等因素的影响,信号中的噪声占比不断提高,使信号逐渐"微弱"。针对海洋环境下的舰船通信微弱信号增强问题,本文采用了基于噪声随机共振理论的信号增强技术,使随机噪声与通信信号产生共振,提高通信信号的强度。分别从随机信号的参数优化算法、随机共振理论和微弱信号增强系统的开发等多个方面进行介绍。
In the process of signal transmission of ship communication system, due to the influence of marine meteorological conditions, interference noise and other factors, the proportion of noise in the signal continues to increase, making the signal gradually "weak". Aiming at the problem of weak signal enhancement of ship communication in marine environment,this paper adopts the signal enhancement technology based on noise random vibration theory, so that the random noise and communication signal can be generated simultaneously vibration, improve the strength of the communication signal. This paper introduces the parameter optimization algorithm of stochastic signal, stochastic resonance theory and the development of weak signal enhancement system.
