| Abstract: | According to the characteristics of multipath propagation in short wave channels, we apply the convolutional homomorphism filtering technique and the complex time domain analysis method of spectrum in order to resist signal fading resulting from multipath propagation. The research shows that these techniques are effectice which can resist signal fading resulting from multipath propagation, and are helpful for decreasing the root mean square error of the output and improving the transmission quality of the signals. |
