Abstract
A convolutionally encoded bit stream is generated and employs a greater number of transmitted parity bits than input data bits. The encoded bit stream is decoded through the use of Exclusive OR operations upon a succession of lengths of received party bits. Non-zero Exclusive OR results determine probable parity bit corrections. Those corrections are used to alter the received, encoded parity bit stream. The altered bit stream is then converted into a data bit stream in accordance with subsequent Exclusive OR operations and a decoding table.
