MIMO Multiuser CDMA System Design, Simulation, and Performance

This project provides a comprehensive exploration of Multiple Input Multiple Output (MIMO) multiuser Code Division Multiple Access (CDMA) systems, focusing on design, simulation, and performance evaluation. It begins with an introduction to MIMO technology and its advantages over traditional communication systems, highlighting the requirements for effective MIMO operation. The project includes the design and simulation of a CDMA system using MATLAB, comparing Walsh code and Gold code spreading techniques. It further delves into single-user MIMO design with two transmitters and two receivers, multi-user CDMA with error correction, and MIMO multiuser receiver design with forward error correction. Performance analysis is conducted for matched filter, decorrelation, and MMSE detectors. The project concludes with simulations of 1000 frames for each SNR to generate MMSE performance, ultimately providing insights into resource allocation and the benefits of CDMA over other multiple access methods like FDMA and TDMA. Desklib provides students with access to this and other solved assignments.
