第三节积分检出调相系统采用相干检测的方法进行接收,抗白高斯噪声能力强,工作可靠。下面首先讨论一下理论基础。发送端发送的信息码调相波,在通道传输
The third point detection phase modulation system uses coherent detection method to receive anti-white Gaussian noise ability, reliable work. The following first to discuss the theoretical basis. The sender sends the information code phase modulation wave, transmitted in the channel
