APPARATUS AND METHOD FOR GENERATING SINGLE CARRIER SIGNAL

摘要

PROBLEM TO BE SOLVED: To compensate for deterioration in modulation properties caused by a difference of operation times between an in-phase signal and a quadrature signal of a digital quadrature modulator.

SOLUTION: A transmission signal generating apparatus is configured by providing a signal point setting means (12) for setting a compensation signal point for correcting a signal point arrangement position error in accordance with the error caused by an operation timing error of a digital quadrature modulator and a data mapping means (11) for assigning a digital information signal to be transmitted on the basis of the signal point setting means, and by performing digital modulation (13) and digital quadrature modulation (15) on the basis of signal point information assigned by the data mapping means.
