Software Implementation of General Channel Capacity Iterative Algorithm

In this documentation, we will implement a general channel capacity iterative algorithm using MATLAB programming. This algorithm can be applied to solve various types of channel capacity calculation problems in communication systems. The implementation leverages MATLAB's powerful computational capabilities, including matrix operations, loop structures, and conditional statements to design and optimize the iterative algorithm. Key programming aspects involve implementing the Blahut-Arimoto algorithm framework, where we'll use probability distribution updates through matrix multiplications and convergence checks using while-loops with tolerance thresholds. During the development process, we will employ debugging tools and performance profiling to gradually enhance the algorithm's efficiency and numerical accuracy. The final implementation will include comprehensive testing with different channel models, result visualization using MATLAB's plotting functions, and performance evaluation through convergence rate analysis and computational complexity assessment. Necessary optimizations will be applied based on the algorithm's behavior observed during simulation runs.
