Distortion compensation circuit, transmitting apparatus and distortion compensating method

A transmitting apparatus for transmitting a signal whose distortion characteristics are compensated for, comprising:

• a distortion compensating coefficient calculator that calculates a distortion compensating coefficient to be used for compensation of the distortion characteristics by comparing an input signal with the signal obtained by feeding back a transmission signal;
• a distortion compensating operation unit that performs operation of the distortion compensation on the input signal, using a variably set bit format and the distortion compensating coefficient calculated by the distortion compensating coefficient calculator, to output a signal after a distortion compensating operation;
• and,
• an amplifier that generates the transmission signal by amplifying the signal after distortion compensating operation output from the distortion compensating operation unit.
