摘要： Devices and methods for the cancellation for and identification of crosstalk for different application cases, particularly for near-end crosstalk (NEXT), are known. Too little attention is paid to the situation of non-reciprocally coupled systems. Therefore, devices and methods for cancellation and identification of far-end crosstalk (FEXT), which enable a reliable identification of an unknown system, are lacking in practice.In order to allow cancellation of FEXT, where wire pairs of a bundle of transmission lines are non-reciprocally coupled, the device according to the present invention for cancellation for and identification of interfering signals in a communication system possess at least a cancellation circuit, which is connected downstream to dead time elements, an interference characteristic detection device and a cancellation control unit, which controls the setting of filter coefficients of an adaptive filter and the cancellation signal source, wherein the adaptive filter is designed as a digital cancellation filter having filter coefficients separated in time by a first delay element having the delay time T, and having an adjustable additional delay time t, whereby the setting of the additional delay time τ takes place together with the setting of filter coefficients.

摘要： A device and method for secondary radar signal reception with quasi-dynamic or dynamic sectoring of a space to be monitored. The device includes at least one antenna assembly including antenna elements for the reception of transmitted secondary radar signals, a signal processing unit connected via a connection point to the antenna elements for the joint processing of received antenna signals, outputs associated with a couple matrix in the signal processing unit and individual receivers. The couple matrix includes adjustable coefficients for sectoring of the space to be monitored and for performing a superposition of the antenna signals using a multiplicative-additive combination of the received antenna signals. In the case of dynamic sectoring of the space, each receiver receives for each receipt telegram another weighted superposition of the antenna signals with certain couple coefficients, and in the case of quasi-dynamic sectoring the adjustable coefficients are fixed over a longer time period.
