Radio Transmitter and Pilot Signal Inserting Method

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.
