  • Method and apparatus for sequentially decoding a digital stream encoded by a convolution type error-correcting code
    Patent number: 5329536
    Abstract: A method and apparatus for sequential decoding using the stack algorithm. A stack is used which is small in size and which has a leaky bottom. A counter stores the total count of nodes observed so as to abandon decoding if this count exceeds a fixed value. A comparator continuously compares the metric at the top of the stack with the largest metric lost from the bottom of the stack as stored in a memory. A small memory stores the path scanned through the logic tree, thereby directly providing the decoded block.
