Development of variable-rate Viterbi decoder and its performance characteristics
Abstract
This paper presents the configuration of the variable-rate Viterbi decoder which was newly developed based on a concept of punctured convolutional coding, and the performance characteristics of punctured codes of rates 1/2 through 16/17 are clarified by hardware experiments and theoretical calculations. Obtained results indicate that the developed codec will be quite useful for effective use of the power and bandwidth of the digital satellite communication systems.
