LTE downlink link adaptation technology for spatial multiplexing closed-loop feedback primarily involves CQI, PMI, RI estimation, adaptive modulation, and precoding with implementation insights for network optimization algorithms.
Application Context: This simulator enables performance evaluation of downlink shared channels in LTE systems for both SISO and MIMO configurations, supporting open-loop spatial multiplexing and transmit diversity transmission modes. The model utilizes post-equalization SINR at the physical layer and incorporates pre-computed fading parameters representing individual interference components. This architecture allows offline pre-generation of fading parameters, significantly reducing computational complexity during runtime execution. Key Technologies: The core simulation file for LTE link-level simulation is lte_sim_main.m. While simulations are typically executed through batch files like lte_sim_launcher.m, which handles configuration loading and simulation orchestration, the main algorithm resides in the primary simulation file containing the core signal processing chain.
