Abstract : The patent relates to a noisy forward communication channel employed to transfer data which has been symbolically coded and also to transfer correction instructions; a noiseless feedback channel is used to return each symbol as it is received to the sending station. The apparatus transfers binary digital data without excessive redundancy, delay or complexity by correcting transmission errors by means of correction instructions as opposed to retransmitting the entire block of data.
