Detailed Documentation

In the link-level simulation of the MIMO-OFDM system, we implemented a 2x2 transceiver antenna configuration and 64 OFDM subcarriers per symbol. To facilitate deeper understanding of MIMO-OFDM systems and iterative receiver principles, we employed iterative detection algorithms in the simulation code. The implementation typically includes modules for channel estimation, QR decomposition for signal detection, and soft-decision feedback loops that progressively refine symbol estimates through multiple iterations. This approach allows comprehensive analysis of system working principles and performance characteristics, with key functions handling spatial multiplexing, cyclic prefix operations, and iterative interference cancellation between antenna streams.
