Abstract:
1. A system for detecting and decoding digital information comprising: a first detector that receives a bit sequence and processes the bit sequence to generate a first hard output and a first soft output, wherein the first detector is a soft-output Viterbi algorithm (SOVA) detector that uses single parity (SOVASP) to generate the first hard and soft outputs; a single decoding operation channel decoder that performs either a row or column decoding operation, the single decoding operation channel decoder receiving the first hard and soft outputs generated by the channel detector, the single decoding operation channel decoder processing the first hard and soft outputs in a non-iterative manner to generate a second hard output; and a second detector that receives the second hard output and processes the second hard output to generate at least a third hard output.
