Title:

TRANSMITTING METHOD AND TRANSMITTER APPARATUS

Document Type and Number:

WIPO Patent Application WO/2004/032345

Kind Code:

A1

Abstract:

A transmitting method and a transmitter apparatus wherein no manual adjustments are required, the delay amount of delay means is automatically so adjusted as to minimize distortion components outside the band of signals to be transmitted, and wherein correct timing is realized. In this transmitter apparatus, first delay means adjusts the control timing of a voltage that controls power-amplifying means. A distributor feeds back a part of an output from the power-amplifying means. Distortion-adjusting means uses a signal fed back by the distributor to calculate the distortion components of a transmitted signal, and automatically so adjusts the delay amount of the first delay means as to minimize the distortion components. This eliminates the necessity of manual adjustments, reduces the distortion, and provides a high efficiency of power supply.
