Simulation of Precoding Techniques for Multiuser MIMO Systems

This paper presents a simulation study on precoding techniques for multiuser MIMO systems. We have conducted simulations focusing on bit error rate and channel capacity based on the signal-to-leakage-and-noise ratio (SLNR) criterion, along with proposing several enhanced algorithms. The implementation involves MATLAB code for channel matrix generation, precoding matrix calculation, and performance metric evaluation. The research provides original reference materials and simulation plots that demonstrate comparative performance between zero-forcing precoding, single-user precoding, and SLNR-based algorithms. Key algorithms are implemented using matrix operations and optimization techniques to handle multiple users simultaneously. This work, recently completed as an outstanding graduation project, offers comprehensive documentation and reliable simulation results available for download, ensuring confidence in usage for further research and development.
