Comprehensive MIMO-Related MATLAB Simulations

This article presents comprehensive MATLAB simulations focused on Multiple-Input Multiple-Output (MIMO) systems. The implementation covers channel ergodic capacity analysis and various channel modeling techniques. For channel ergodic capacity, we investigate capacity performance under different scenarios using MATLAB's communication toolbox functions, comparing variations through Monte Carlo simulations that calculate average capacity over multiple channel realizations. The channel modeling section explores different channel types (Rayleigh, Rician, and spatial correlation models) implemented using eigenvalue decomposition and random matrix generation functions. We analyze their characteristics through covariance matrix computations and apply them to relevant scenarios using adaptive modulation and coding schemes. These simulation experiments provide practical MATLAB code examples for better understanding and application of MIMO technology, while establishing a foundation for further research through modifiable simulation parameters and extendable code architecture.
