MATLAB simulation and simulation of Rayleigh fading multipath channel
Rayleigh fading is one of the common channel characteristics in wireless communications, which is caused by multipath propagation. In this article, we will use MATLAB to simulate and simulate Rayleigh fading multipath channels. We will provide corresponding source code to help you understand and implement this process.
First, let us understand the principle of Rayleigh fading multipath channel. In wireless communications, signals undergo reflection, scattering, and diffraction through multiple paths during propagation. Differences in the length and phase of these paths cause changes in the amplitude and phase of the signal, causing channel fading. Rayleigh fading multipath channel refers to a multipath channel that has no direct path and consists only of scattering paths.
The following is a code that uses MATLAB to simulate Rayleigh fading multipath channels:
