Abstract: A receiver and a method are applied in a wireless communication system for detecting interference with a coexisting radar system. A signal received from an antenna is fed through an analog part and a subsequent digital part of said receiver. The receiver has an element with a-priori known attenuation values for a predefined set of frequencies, a first branch-off element for deriving a first detection signal from the signal before the element and a second branch-off element for deriving a second detection signal from the signal after the element. The receiver processes the first and the second detection signal such that a difference between the first and second detection signal is comparable with a threshold value, where the threshold value depends on the a-priori known attenuation values of the element. Depending on the comparison result, a frequency is identified as interfering or not a co-existing radar system.

Abstract: The device has a base element and a switch element with auxiliary electrodes in the lateral direction. A voltage is applied to electrodes and the auxiliary electrodes to open switch contacts so the electrodes and auxiliary electrodes have first and second potentials, resulting in electrode and auxiliary electrode surface areas with positive and negative charge carriers in the lateral direction and equal charge carriers in the orthogonal direction. The device has a base element and a switch element with auxiliary electrodes (EG,ES) in the lateral direction to which a voltage can be applied. The voltage is applied to electrodes (HG,HS) and the auxiliary electrodes to open switch contacts so the electrodes have a first potential (U1) and the auxiliary electrodes a second potential (U2), resulting in surface areas on the electrodes and auxiliary electrodes with positive and negative charge carriers in the lateral direction and with equal charge carriers in the orthogonal direction. AN Independent claim is also included for the following: a portable terminal with an inventive device.

Abstract: Un receptor para detectar interferencias en un sistema de comunicaciones inalámbricas, en el que se recibe una señal de una antena (100) y se suministra a una ruta de una señal en una parte analógica (200) a una parte digital subsiguiente (300), que comprende -un primer elemento de bifurcación (230, 252) para derivar de la señal en la ruta de la señal una primera señal de detección (S10, S22), -un segundo elemento de bifurcación (251, 270) para derivar de la señal en la ruta de la señal una segunda señal de detección (S21, S30, S20), -un elemento (240, 260), colocado en la ruta de la señal entre dicho primer (230, 252) y dicho segundo (251, 270) elemento de bifurcación, en el que el elemento (240, 260) tiene unos valores de atenuación conocidos a priori para un conjunto de frecuencias predefinidas, y -medios de procesamiento (400) para procesar la primera (S10, S22) y la segunda (S21, S30, S20) señal de detección de forma que la diferencia entre la primera (S10, S22) y la segunda (S21, S30,S20) señal de detección se compara con un valor de umbral, donde el valor de umbral depende de los valores de atenuación conocidos a priori del elemento (240, 260).
