Abstract
The present invention relates to a coding apparatus and a coding method by which the circuit scale can be reduced without changing the operation speed in coding of a linear code. An adderintegrates the product of an information word Dof six bits supplied from a cyclic shift circuitand the information part of a check matrix H corresponding to the information for each row in a unit of six rows and supplies the integrated value as a sum Dto a RAM. The RAMstores the sum D. Further, the RAMsuccessively reads out sums Dof 2 bits stored already therein and supplies the read out sums Das sums Dto an accumulatorthrough an interleaver. The accumulatorintegrates the sums Dand outputs a sum Dobtained as a result of the integration as a parity bit p of a codeword c through a selector. The present invention can be applied to an apparatus of a broadcasting station which transmits a satellite broadcast.
