A Comparison of Rate 1/n Convolutional Codes over a Simulated Noisy Channel Using the Viterbi Decoding Algorithm

摘要

The application of error detection and correction codes has advanced markedly with the advent of digital technology. However, the strides made towards employing the techniques, encoding and decoding, properly have been rather limited by the Naval forces in the United States. This paper develops a computer program, which if used properly, would aid in deciding what error correcting scheme is best suited for a specific channel. The results obtained from testing a rate 1/n convolutional code, over a simulated channel, using a Viterbi decoder shows that this is an effective analysis procedure. Though the test runs were lengthy, much of the time required was for noise simulation. This would not be a factor if actual channel noise recordings had been available.
