Channel Capacity and Channel Estimation MATLAB Implementation

This package provides a detailed MATLAB source program that thoroughly addresses both channel capacity and channel estimation components. The implementation begins with channel capacity calculations, which determine the maximum achievable data transmission rate under specific channel conditions. The code includes functions for computing capacity metrics using Shannon's theorem formulations and analyzing capacity performance under different signal-to-noise ratio scenarios. Key algorithms incorporate matrix operations for multi-antenna systems (MIMO configurations) and probability distribution calculations for capacity bound estimations. Furthermore, the program implements sophisticated channel estimation methodologies that utilize received signal samples to reconstruct channel state information and parameters. The implementation features both pilot-based and blind estimation approaches, employing techniques like Least Squares (LS) and Minimum Mean Square Error (MMSE) estimators. The code includes modules for channel parameter extraction, estimation error analysis, and optimization routines to enhance estimation accuracy through iterative refinement algorithms. The comprehensive nature of this source code provides researchers and engineers with practical tools for understanding, implementing, and optimizing fundamental communication system concepts. The modular structure allows for easy integration of additional functionalities while maintaining computational efficiency through vectorized operations and optimized signal processing functions.
