BIAS MODULATION APPARATUS, AND APPARATUS AND METHOD FOR TRANSMITTING SIGNAL FOR WIDEBAND MOBILE COMMUNICATION USING THE SAME |
摘要 |
In a wideband mobile communication system, a signal transmitting apparatus separates an envelope curve signal which is size information and a phase signal which is phase information from a signal to transmit, and compares the envelope curve signal with a predetermined voltage. The signal transmitting apparatus performs active bias control that amplifies and outputs an envelope curve signal according to different driving voltages based on a comparison result, and supplies a bias voltage to a power amplifier that amplifies a phase signal based on the amplified signal.
