Convolution decoding terminated by an error detection block code with distributed parity bits

摘要

An improved encoding technique improves the error detection provided in conventional communication systems. Traditional encoding systems for communication systems often utilize channel-coding in the form of block-coding and convolutional encoding. Block-coding typically utilizes parity bits for error detection. These parity bits are typically placed as a block at the end of the data frame. The present invention provides an improved encoder and decoder which utilize parity bits placed within the data and spread within the data bits for higher reliability.
