MULTI-CARRIER TRANSMITTER APPARATUS, MULTI-CARRIER RECEIVER APPARATUS, AND MULTI-CARRIER COMMUNICATION METHOD

摘要

A multi-carrier transmitter apparatus (100) receives line quality information of each sub-carrier from a multi-carrier receiver apparatus (200), and uses an interleave pattern setting part (108) to set an interleave pattern in accordance with the line quality of each sub-carrier. An interleaver (106) uses the set interleave pattern to interleave the I and Q components of a symbol. As a result, the diversity gain in the modulation diversity modulation/demodulation can be optimized in accordance with the line quality.
