Resource Overview
This program simulates the detection performance of two V-BLAST receivers (Zero-Forcing and Minimum Mean Square Error) and plots Bit Error Rate versus Signal-to-Noise Ratio curves. The simulation implements layered signal detection algorithms with matrix inversion operations for interference cancellation.
Detailed Documentation
In this paper, we conduct simulations to evaluate the detection performance of two V-BLAST receiver algorithms - Zero-Forcing (ZF) and Minimum Mean Square Error (MMSE). The implementation involves layered signal detection where ZF uses pseudo-inverse matrix operations while MMSE incorporates noise statistics in its weight calculations. We generate BER-SNR curves that demonstrate the trade-off between interference cancellation and noise enhancement in these detectors. These experimental results provide valuable insights for performance assessment and selection criteria of MIMO receiver architectures in wireless communication systems.
