Transmission method and reception method using a transmitter and receiver, as well as multi-carrier transmission scheme of multi-carrier transmission scheme

摘要

It is an object of the present invention is without lowering the transmission efficiency and reduce inter-carrier interference occurring in the phase variation and frequency variation, or amplitude variation,. With canceling filter portion (223) to the receiver, I will reduce the inter-carrier interference generated by such phase variation frequency variation, or amplitude variation, by the filtering process. With a pre-coding unit (211) to the sender, to facilitate the determination of the demodulated data in the (224) vector demodulation section of the receiver by the pre-processing code. Or, with a trellis decoding unit (225) to the receiver, to decode the demodulated data by trellis decoding process.
