Abstract

PURPOSE: To realize an error correction system which features a reduced number of the redundancy characters for error correction as well as a quick and accurate transmission of the digital code.
CONSTITUTION: The digital information supplied from line 1 undergoes the interface via code process circuit (Di)A-1 for the digital code to have the code process through which, for example, the input one word is changed to two words, and is then supplied to transmitting error correction device A-2(Ept) via line 2. The input given from line 1 and the output of line 2 have different formats to each other since they were processed at circuit A-1. Device A-2 applies the parity code for correction to the input code to then send it to the transmitter comprising transmitter T and the antenna as well as to antenna A-3 via line 3. Then A-3 transmits the digital signals encoded at A-2 via the radio circuit 4. For circuit 4, the transmission signals are received at station B from station A. And B-3 consists of the antenna and the receiver, and the output obtained by demodulating the received signals is supplied to receiving error correction device B-2(EPR) via line 5. Thus the error correction is carried out with every character via the information and the parity code.
