Abstract :

Multiple Input Multiple Output (MIMO) Technology Plays A Vital Role In Modern Wireless Communication Systems Due To Its Ability To Significantly Enhance Data Rate, Reliability, And Spectral Efficiency Without Requiring Additional Bandwidth Or Transmit Power. This Paper Presents A Comprehensive Performance Analysis Of A MIMO Wireless Communication System Using MATLAB Simulation. The Study Evaluates Key Performance Metrics Such As Bit Error Rate (BER), Channel Capacity, Signal-to-noise Ratio (SNR), And Diversity Gain Under Various Modulation Schemes And Channel Conditions. Different MIMO Configurations, Including 2×2 And 4×4 Antenna Systems, Are Analyzed To Demonstrate The Impact Of Antenna Diversity On System Performance. Rayleigh Fading And Additive White Gaussian Noise (AWGN) Channels Are Considered To Model Realistic Wireless Environments. The Simulation Results Clearly Indicate That MIMO Systems Outperform Conventional Single Input Single Output (SISO) Systems In Terms Of Error Performance And Throughput. Additionally, Spatial Diversity And Spatial Multiplexing Techniques Are Examined To Highlight Their Effectiveness In Mitigating Fading And Improving Link Reliability. The MATLAB-based Analysis Provides Valuable Insights Into The Design And Optimization Of High-performance Wireless Communication Systems, Making It A Useful Reference For Researchers And Engineers Working In Next-generation Communication Technologies Such As 4G, 5G, And Beyond. Keywords: MIMO Systems, MATLAB Simulation, Bit Error Rate (BER), Channel Capacity, Wireless Communication, Rayleigh Fading, AWGN Channel, Spatial Diversity
