A turbo encoder comprises rearranging means for arranging, in a buffer of N (natural number) rows x M (natural number) columns, a random sequence produced by use of prime numbers; performing, by use of the random sequences, bit rearrangement row by row to thereby produce N random sequences; mapping data sequences of interleaver-length to the rearranged N random sequences; performing an row rearrangement of the mapped data sequences in accordance with a predetermined rule to thereby produce a final rearranged pattern; and finally, reading out the produced rearranged pattern column by column.
