A device a radio communication device may be provided. The radio communication device may include: a movement characteristics determination circuit configured to determine a movement characteristics of the radio communication device; a beam pattern determination circuit configured to determine a beam pattern based on the determined movement characteristics; and an antenna controller configured to control an antenna to operate using the determined beam pattern.

Radio communication devices and methods for controlling a radio communication device

Various embodiments include a power amplifier with crest factor reduction embodied by first circuitry for producing a correlated out-of-band noise signal for controlling the adjacent channel leakage ratio (ACLR) of a communication device; and second circuitry for providing an output signal for controlling the error vector magnitude (EVM) of a digital radio. The ACLR and the EVM are concurrently individually controllable. Additional apparatus is described.

Operating point setting of an amplifier

A distortion estimation apparatus for estimating distortion includes a feedback element, a nonlinearity determiner, and a distortion simulator. The feedback element provides a feedback signal derived from a distorted output signal of the distorting element. A signal processing quality of the feedback element is lower than an associated signal property of the distorted output signal. The nonlinearity determiner receives the feedback signal and an input signal to the distorting element or a signal derived from the input signal. The nonlinearity determiner determines an estimated transmission characteristic of the distorting element by relating signal properties of the feedback signal and the input signal or the signal derived from the input signal. The distortion simulator estimates the distortion caused by the distorting element based on the input signal or the signal derived from the input signal and the estimated transmission characteristic.

A controller for controlling a signal processor includes a transformation unit and a control unit. The transformation unit is configured to generate at least one amplitude-modulation-to-phase-modulation-distortion within a signal, output by using the signal processor according to a signal processing, based on generated at least one amplitude-modulation-to-amplitude-modulation-distortion of the signal. The control unit is configured to adjust the signal processing of the signal processor so as to minimize the at least one amplitude-modulation-to-phase-modulation-distortion.
