MATLAB Subfunctions for Multipath Channel Modeling

This document presents MATLAB subfunction implementations for multipath channel modeling, including the Jakes model. The MATLAB-written multipath channel models simulate wireless communication multipath propagation phenomena. In these models, users can define multiple paths with their respective fading parameters to emulate realistic channel environments. The Jakes model, a commonly used approach, generates signals with multipath effects based on statistical properties of plane waves. These implementations typically involve defining Doppler spread, path delays, and attenuation factors through parameter structures. Key functions may include channel initialization, signal propagation through multiple paths, and combining received signals with appropriate phase shifts and delays. Through these models, researchers can better understand and study multipath propagation phenomena in wireless communications, providing valuable references for system design and performance evaluation. The code structure often includes main simulation loops, path gain calculations, and statistical analysis of channel characteristics.
