MATLAB Code Implementation for Limited Feedback Simulation

This document provides an in-depth discussion of the limited feedback simulation program. The implementation focuses on system behavior when the number of feedback bits remains fixed, including detailed analysis of its advantages and limitations. The MATLAB code employs quantization algorithms to map channel state information (CSI) to limited feedback bits, using codebook-based approaches for efficient feedback representation. The program enables testing with different feedback bit values through parameterized functions, allowing comparative analysis of system performance metrics like throughput and error rates. Key functions include adaptive codebook generation and quantization error calculation modules that help evaluate the trade-off between feedback overhead and system performance. Additional variables such as channel models, signal-to-noise ratios, and modulation schemes can be integrated into the simulation framework to further explore limited feedback concepts. The code structure supports modular testing with configurable parameters through dedicated initialization scripts and result visualization functions. This enhanced discussion aims to deepen understanding of limited feedback simulation methodologies, with practical MATLAB implementation examples demonstrating real-world application scenarios and performance optimization techniques.
