Title:
COMMUNICATION METHOD AND RADIO TRANSMITTER
Document Type and Number:
WIPO Patent Application WO/2006/046696
Kind Code:
A1
Abstract:
[PROBLEMS] To perform a radio transmission even to the other end of communication, which has a limited bandwidth in which transmission and reception can be performed, without giving any affection of offset in DC components. [MEANS FOR SOLVING PROBLEMS] A radio transmitter, which is applied to OFDMA communication system in which a plurality of different terminals use OFDM signals to have communication at the same time, comprises a mapping part (4) that assigns transmission powers to respective ones of subcarriers, selects a subcarrier, to which the lowest transmission power is assigned, from among those assigned transmission powers, and modulates transmitted data for each of communication slots to output modulated data; and transmitting parts (8,9,10) that use the subcarriers to transmit radio signals including the modulated data.
