MATLAB Simulation of VBLAST-OFDM System with Graphical Interface

We developed a detailed MATLAB simulation for the VBLAST-OFDM system with an intuitive graphical user interface and comprehensive simulation plots to effectively visualize the results. The simulation implements advanced VBLAST-OFDM techniques through MATLAB programming, utilizing key functions for signal processing, matrix operations, and communication system modeling. The implementation includes algorithms for vertical Bell Laboratories layered space-time (VBLAST) processing combined with orthogonal frequency-division multiplexing (OFDM) modulation, featuring channel encoding, MIMO signal detection, and error rate calculation modules. Through this simulation, we can thoroughly analyze the performance characteristics of VBLAST-OFDM systems, including capacity analysis, interference resistance evaluation, and transmission efficiency metrics. The simulation results demonstrate that VBLAST-OFDM exhibits outstanding performance in channel capacity and interference immunity, achieving high transmission efficiency and reliability through optimal signal detection algorithms and spatial multiplexing techniques. This simulation study provides significant value for both theoretical analysis and practical applications, offering robust support for further research and development of VBLAST-OFDM technology through reproducible code implementation and performance benchmarking.
