Radio transmitting device and radio transmitting method

Abstract

The amount of distortion of the output signal increases due to a difference in delay times in a plurality of paths in a radio transmitting device transmitting RF signals in a plurality of bands, therefore, a radio transmitting device according to an exemplary aspect of the present invention includes: a multi-band RF signal generator making each of a plurality of input baseband signals carried by a carrier wave with each of different frequencies, and outputting the carrier wave as a radio frequency signal; a power amplifier amplifying and outputting the radio frequency signal; a distortion compensation control signal generating unit applying a distortion compensating function, which compensates a distortion characteristic of the power amplifier, to the each of the plurality of input baseband signals; and a transmitter delay correction unit correcting a difference in delays which the plurality of input baseband signals receive respectively in the multi-band RF signal generator.
