MATLAB Implementation of Rayleigh Channel Simulation Model for Mobile Communications

I present a MATLAB program designed for simulating Rayleigh channel models in mobile communications. This program facilitates deeper understanding of channel transmission characteristics in wireless communication systems. The Rayleigh channel represents a common wireless propagation model that enables simulation and analysis of signal transmission behavior in wireless environments. The MATLAB implementation generates Rayleigh channel simulation results through configurable parameters including Doppler shift, delay spread, and multipath components. Key functions involve generating complex Gaussian random variables for in-phase and quadrature components, implementing Jakes' model for Doppler spectrum simulation, and calculating channel impulse responses. The program supports parameter adjustment for different scenarios and provides analytical tools for evaluating signal quality metrics like bit error rate and channel capacity. Through this simulation tool, researchers can investigate and optimize mobile communication system performance to enhance signal transmission quality and user experience by analyzing fading characteristics, diversity techniques, and equalization methods.
