摘要：The present invention relates to a coding apparatus and a coding method bywhich the circuit scale can be reduced without changing the operation speed in coding ofa linear code. An adder 13 integrates the product of an information word D13 of six bitssupplied from a cyclic shift circuit 12 and the information part of a check matrix Hcorresponding to the information for each row in a unit of six rows and supplies theintegrated value as a sum D15 to a RAM 14. The RAM 14 stores the sum D15.. Further,the RAM 14 successively reads out sums D16 of 2 bits stored already therein and
supplies the read out sums D16 as sums D17 to an accumulator 16 through an interleaver15. The accumulator 16 integrates the sums D17 and outputs a sum D18 obtained as aresult of the integration as a parity bit p of a codeword c through a selector 17. Thepresent invention can be applied to an apparatus of a broadcasting station whichtransmits a satellite broadcast.
