摘要
针对短波信道多径传播的特点，采用卷积型滤波技术和复时谱分析方法，抗多径传播引起的信号衰落．研究结果表明，该方法能够更好的滤除干扰，改变传输信道质量．
According to the characteristics of multipath in short -wave channels we apple the convolutional homomorphism filtering technique and the complex time-domain analysis method of spectrum in order to resist signal fading resuling from multipath propagation The research these techniques are effective which can resist signal fading resulting from multipath propagation ,and are helpful for improving the transmission quali- ty of the signals
