Abstract

PURPOSE:To increase a data transmission speed up to the bit rate of a circuit by sending data and its parity information through individual circuits in satellite communication. CONSTITUTION:Data to be transmitted is sent to an error correcting and receiving circuit 70 through a series transmission channel 61. Further, said data is inputted to a parity generator 3 as well to generate parity information, which is transmitted to said circuit 70 through a channel 62. In the circuit 70, the data is inputted to a parity generator 8 and the parity information is outputted to a terminal 8B while delayed data appears at a terminal 8A. An exclusive OR circuit 9 receives both the pieces of parity information and sends its output to an error correction bit generating circuit 10, and an error correction bit to be outputted is exclusively ORed with the delayed data by a circuit 11 to output corrected data.
