Research on Adaptive Threshold of Received Signal in Communication System被引量：3
《Optics and Photonics Journal》2021年第1期1-11,共11页Xizheng Ke Xukuan Ji 
When the light beam propagates in the atmosphere, the signal will be absorbed and scattered by the gas molecules and water mist in the atmosphere, which will cause the loss of power rate. The complex atmospheric envir...
