Abstract: A transmitting method and a transmitter apparatus, which need no manual adjustment, are disclosed. A delay amount is automatically adjusted such that an out-of-band distortion component of a transmission signal is minimized, and a correct timing is produced by the method and the apparatus. In this transmitter apparatus, a first delay adjusts a control timing over a voltage that controls a power amplifier, and a distributor distributes an output from the power amplifier in order to feedback parts of the output. A distortion adjusting units calculating a distortion component of the transmission signal by using the signal fed back by the distributor, and adjusts automatically a delay amount of the first delay so as to minimize the distortion component. This structure allows eliminating manual adjustment, and obtaining high power-efficiency with fewer distortions.

Abstract: One embodiment of the present subject matter includes a method of receiving an input signal. The method, in various embodiments, includes detecting a peak of the input signal and detecting an envelope of the input signal. In various embodiments, the peak and envelope are used to identify out-of-band blocking signals and to adjust gain control. The method also includes comparing the peak to a first threshold Tp and comparing the envelope to a second threshold Te. In the method, if the peak is above the first threshold and the envelope is below the second threshold, then ignoring the input signal. If the envelope is above the second threshold, the method includes applying automatic gain control to decode information encoded in the input signal.
