Abstract
A determinate-state convolutional code is formed from a conventional convolutional code by pruning away some of the possible state transitions in the decoding trellis. The type of staged power transfer used in determinate-state convolutional codes proves to be an extremely efficient way of enhancing the performance of a concatenated coding system. This article analyzes the decoder complexity and free distances of these new codes and provides extensive simulation results of their performance at the low signal-to-noise ratios where a real communications system would operate. The article concludes with concise, practical examples.
