Abstract
Counter control sectionincrements a row number and column number on a two-dimensional array for a block interleave expressed by a matrix two-dimensional array, outputs the incremented numbers as the read address values, bit inversion apparatusperforms bit inversion using the read address values as inputs, column conversion sectionoutputs the address values corresponding to the bit inversion output values and the column numbers from counter control sectionas the column conversion values, shift registerbit-shifts the output values of bit inversion apparatusand outputs as the address offset values, adderadds up the address offset values and column conversion values and size comparison sectioncompares the addition value with the interleave size and outputs data which is not greater than the interleave size as address values.
