<p>The process of the present invention error corrects subaudible data words that have been transmitted over a voice channel. A data word may be transmitted up to three times (515), 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 (525) is transmitted. If all three repeats of the data word contain uncorrectable errors a bitwise majority vote (519) is performed on the three data words. If the result of majority vote is decodable, an acknowledgment (525) is transmitted to the sender.</p> |
