Abstract
PURPOSE: To make it possible to correct a block error by providing a delay circuit stage and syndrome generating circuit stage consisting of an exclusive-OR circuit and a circuit making cross connections among feedback shift register composed of registers.
CONSTITUTION: Random positive integers are represented by (b) and (m) and (b)- bit parallel information is transmitted as unit block, block by block, in series to a maximum of (qm-1)/(q-1)[q=2b]. Of this data processing system, a system which corrects a block error consists of delay circuits 10-0 and 10-1 and syndrome generating circuit stage 5 composed of exclusive-OR circuit 16 and cross connection circuit 13 which makes a cross connection between "#0" and "#1" feedback registers 12-0 and 12-1 as many as (b), for example, when (b) is "2" and (m) is "3". A block error of input is corrected by the output of circuit 5.
