摘要： A radio transmitter and a pilot signal inserting method are provided for improving throughput. In the radio transmitter, an MCS deciding part (106) selects one of a plurality of modulating systems. An information generating part (108) decides an inserting position of a pilot signal corresponding to the selected modulating system. A modulating part (116) modulates a data signal by the selected modulating system. A signal arranging part (118) inserts the pilot signal into the modulated data signal and changes the inserting position of the pilot signal corresponding to the selected modulating system. A transmission RF part (124) transmits the data signal wherein the pilot signal is inserted.

摘要： Provided is a resource allocation method capable of improving a reception quality when connecting a plurality of sub frames into one frame and performing a communication process for each of the frames. In this method, when a sub frame #1 is transmitted, LRB is selected as a resource allocation format according to CQI fed back from a mobile station and RB having a preferable propagation quality is allocated for transmission data according to the LRB format. When a sub frame #2 is transmitted, the same resource allocation method (LRB) as the head sub frame is used and the transmission data is allocated for the same RB. When a sub frame #3 is transmitted, the resource allocation method is switched from the sub frame #1 and the sub frame #2 and the transmission data is allocated for RB by using the DRB format.

An Ich arrangement unit (103) and a Qch arrangement unit (104) arrange the Ich and Qch, respectively, in a plurality of sub-carriers constituting an OFDM symbols, and output the same to a synthesization unit (105). This synthesization unit (105) synthesizes the Ich and Qch arranged for each sub-carrier, to create the synthesized symbol.
