Simulation of V-BLAST Systems and Their Detection Algorithms

This program is designed to simulate V-BLAST systems and their detection algorithms to evaluate their performance characteristics. It supports multiple modulation schemes, including BPSK, QPSK, 16QAM, and 64QAM, with corresponding constellation mapping functions implemented for symbol encoding/decoding. The detection algorithms feature modular implementations of ML (exhaustive search-based maximum likelihood), MMSE (using regularization for noise robustness), ZF (linear pseudo-inverse solution), and SIC-ZF (sequential interference cancellation with zero-forcing preprocessing). The simulation framework incorporates configurable channel models to test performance under various channel conditions, enabling comprehensive system evaluation. We believe this program provides valuable reference for related research and supports optimization efforts for V-BLAST systems through comparative algorithm analysis and BER (Bit Error Rate) performance metrics.
