BER Performance Simulation for MIMO Systems with QPSK Modulation

This study conducts comprehensive simulation analysis of Bit Error Rate (BER) performance in MIMO systems using Quadrature Phase Shift Keying (QPSK) modulation over Gaussian Rayleigh fading channels. Through simulation experiments, we generate BER curves that provide insights into system performance under various channel conditions. The simulation typically involves generating random QPSK symbols, applying MIMO channel matrix transformations with Rayleigh fading coefficients, implementing maximum likelihood or zero-forcing detection algorithms, and calculating BER by comparing transmitted and received symbols. These simulation results are crucial for evaluating and optimizing MIMO system performance, offering valuable guidance for designing and deploying advanced wireless communication systems. The implementation may include key functions for channel matrix generation, signal detection algorithms, and BER calculation modules to ensure accurate performance assessment.
