TRANSMISSION METHOD, TRANSMITTER APPARATUS AND RECEPTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate characteristic that is caused by fading or the like. SOLUTION: There are included encoding parts (11_1 to 11_4) that encode transmission data; a mapping part (3304) that performs such a mapping that encoded data sequentially formed by the encoding parts (11_1 to 11_4) are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver (3301) that interleaves the data symbols. In this way, a small circuit scale can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.
