OFDM COMMUNICATION APPARATUS AND OFDM COMMUNICATION METHOD

摘要

An OFDM communication apparatus that can set an optimum repetition number to data to be transmitted, thereby improving the error rate characteristic and hence the communication quality. In this apparatus, a repetition number deciding part (153) decides, based on quality information outputted from a quality information extracting part (152), a required repetition number. A systematic bit repetition number deciding part (154) decides, based on the repetition number notified of by the repetition number deciding part (153), an optimum repetition number for the systematic bit. A parity bit repetition number deciding part (155) operates similarly. Repetition parts (103-1,103-2) repeat the bits in accordance with instructions from the systematic bit repetition number deciding part (154) and from the parity bit repetition number deciding part (155).
