Abstract

An error detection and correction apparatus includes three threshold logic units which make decisions based on current and previous bit values in a bit stream of block-coded data. One of the threshold logic units decodes the data stream based on an advancing time stream of data. Another threshold logic unit decodes the data stream based on a time-reversed stream of data, and the last threshold logic unit decodes the data stream based on a time-reversed input stream of data and a time-reversed set of decisions made by the first threshold logic unit. Each threshold logic unit generates decisions and a parity check of those decisions Error identification information is compared between the three streams of decisions and parity checks on those decisions, thereby producing error information, which is processed by a circuit which determines which is the most likely data transmitted.
