A PC-based simulator for the design and analysis of convolutional codes using Viterbi decoding

The simulator presented allows the user to interactively design and test convolutional codes using a desktop computer. All parameters such as constraint length, decode depth, and encoder configuration are accessible through a user-friendly menu-driven interface. In addition, the theory of convolutional coding, and an explanation of how error correction is achieved are presented. The maximum-likelihood decoding algorithm is described and the transformation to the Viterbi algorithm is developed.<
