Abstract
The process of the present invention error corrects sub-audible data words that have been transmitted over a voice channel. A data word may be transmitted up to three times if an acknowledge is not received by the transmitter. If any of the three possible repeats of the received data word are decodable, an acknowledgment is transmitted. If all three repeats of the data word contain uncorrectable errors, a bitwise majority vote is performed on the three data words. If the result of the majority vote is decodable, an acknowledgement is transmitted to the sender.
