Simulation of V-BLAST Detection Algorithm for 4x4 MIMO Systems

This program simulates V-BLAST detection algorithms for a 4-transmit 4-receive MIMO system. The implementation features QPSK modulation, quasi-static Rayleigh flat fading channels, and additive white Gaussian noise with zero mean. Four detection schemes (ZF, MMSE, ZF-OSIC, MMSE-OSIC) are compared through bit error rate performance analysis, with code-level descriptions of algorithm implementations.
