MATLAB Code Implementation for Five Channel Models with Technical Descriptions

Below is the directory of MATLAB code implementations for five channel models with detailed technical descriptions: 1. SUI Channel: This widely-used mobile communication channel model employs Stanford University Interim parameters for wireless simulations. Implementation typically involves creating tapped-delay lines with specific Doppler spectra and path loss characteristics using MATLAB's communications toolbox functions. 2. Gaussian Channel: This fundamental channel model is ideal for communication environments with minimal noise interference. The MATLAB implementation generally uses awgn() function to add additive white Gaussian noise to transmitted signals, with configurable signal-to-noise ratio parameters for performance analysis. 3. Rayleigh Channel: This common wireless transmission model effectively characterizes multipath propagation effects. The implementation utilizes Rayleigh fading distribution through rayleighchan() function, modeling signal amplitude variations due to multiple signal paths with specified Doppler shift and delay profile parameters. 4. COST231: This versatile channel model supports both indoor and outdoor transmission scenarios across various communication environments. The code implementation incorporates COST 231 Hata model extensions for urban areas, using path loss calculations based on frequency, antenna height, and distance parameters with built-in correction factors. 5. COST207: This comprehensive channel model accommodates diverse indoor and outdoor transmission requirements. The MATLAB implementation typically features GSM-standardized power delay profiles with six specified tap settings, simulating different urban and rural environments through carefully defined delay spread and Doppler spectrum characteristics. We hope this technical documentation and code implementation guidance proves valuable for your communication system simulations and analysis.
