摘要： A wireless communication link between two communication devices is established. A communication signal for contacting a second communication device is emitted from a first communication device. The communication signal is a first type of wireless data communication. Communications that are configured to transmit and receive data according to a second type of data communication are activated in the first communication device. Upon receipt of the communication signal, communications that are able to transmit and receive data according to the second type of data communication are activated in the second communication device, and the communication link according to the second type of data communication is established.

摘要： A circuit arrangement for determining a frequency drift in a phase locked loop includes a type I phase locked loop having a phase comparator, a charge pump, a loop filter, an oscillator and also a frequency divider in a feedback path of the control loop. A device is coupled to the phase locked loop for the purpose of determining a pulse length of the actuating voltage signal at at least two different times during an operation of the control loop. Furthermore, a computing unit is connected to an output of the device. It is designed for forming a difference between the pulse lengths at the at least two different times, as a result of which a phase and frequency drift of an output signal of the control loop can be determined.

摘要： One embodiment of the present invention relates to a method and apparatus are provided herein for reducing the power consumption of a transmission chain while maintaining an acceptable figure of merit (e.g., linearity). In one embodiment, an adaptive biasing element is configured to perform adaptive biasing to reduce current consumption of a transmission chain by adjusting the operating point of one or more transmission chain elements (e.g., power amplifier, mixer, etc.). However, since adaptive biasing may reduce the linearity of a transmitted signal, its use is limited by the degradation of figure of merit caused by the introduced non-linearities. Accordingly, a pre-distortion element may be configured to perform adaptive digital pre-distortion (DPD) on a transmission chain input signal to account for non-linearities generated through the adaptive biasing, therefore allowing the adaptive biasing to further reduce the current consumption while maintaining an acceptable figure of merit.
摘要翻译： 本发明的一个实施例涉及一种方法和装置，用于在保持可接受的品质因数（例如线性度）的同时降低传输链的功率消耗。 在一个实施例中，自适应偏置元件被配置为执行自适应偏置以通过调整一个或多个传输链元件（例如，功率放大器，混频器等）的工作点来减小传输链的电流消耗。 然而，由于自适应偏置可以降低发射信号的线性度，所以其使用受到引入的非线性引起的品质因数的劣化的限制。 因此，预失真元件可以被配置为在传输链输入信号上执行自适应数字预失真（DPD），以解决通过自适应偏置产生的非线性，从而允许自适应偏置进一步降低电流消耗，同时 保持可接受的品质因数。

摘要： 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.

摘要： A power control system includes a reference path filter used to suppress high frequencies in an input signal and generate a filtered envelope signal, a reference path amplifier to scale the filtered input signal based on a gain signal and generate a reference signal, a signal path amplifier to amplify an RF modulated signal and generate a signal path output signal scaled by a gain of an actuator signal, and a power detector to detect a power associated with the signal path output signal. The system includes an ADC to receive, pre-filter and convert the detected envelope signal into a measurement signal, and a comparator block to receive the reference signal and the measurement signal, and generate an error signal based on the difference, and a controller to generate the actuator signal for controlling the gain of the signal path amplifier based on the error signal.
