Abstract: A system includes at least two photovoltaic modules each comprising a respective module area being substantially perpendicular to the thickness of the corresponding photovoltaic module. Each of the at least two module areas comprises at least one of two first sides being substantially perpendicular to the thickness of the corresponding photovoltaic module and/or two second sides being substantially perpendicular to the thickness of the corresponding photovoltaic module. In this context, the at least two module areas are arranged in a substantially parallel manner with respect to each other and are shifted with respect to each other in an extension direction of the system. In addition to this, the at least two module areas are arranged in a staggering or alternating or ascending or descending manner with respect to an extension plane in the extension direction of t

Abstract: A method is provided for indoor multipath ghosts recognition for a multiple-input-multiple-output radar with collocated antennas. The method includes the step of generating a two-dimensional Range-Doppler map for N number of consecutive radar data frames. The method further includes the step of applying a temporal clustering algorithm to the N number of consecutive radar data frames. Moreover, the method includes the step of applying a linear pattern extraction algorithm on the two-dimensional Range-Doppler map. In this context, the two-dimensional Range-Doppler map comprises detections from at least one target, at least one first-order ghost, and at least one second-order ghost with respect to one wall reflector.

Abstract: A system for providing distributed wireless communication for at least one user equipment with connectivity and/or security against at least one eavesdropper is provided. The system includes wireless communication units and a scheduling unit. In this context, the scheduling unit is configured to schedule a first subset of the wireless communication units for radar sensing in order to gather radar sensing information with respect to the at least one user equipment, the environment of the at least one user equipment, the at least one eavesdropper, the environment of the at least one eavesdropper, or any combination thereof. In addition to this, the scheduling unit is configured to schedule a second subset of the wireless communication units for distributing the wireless communication with respect to the at least one user equipment on the basis of the radar sensing information.

Abstract: In a radar system, a cancellation circuit is described for compensating for the effects of spillover between each transmitter and a receiver. The cancellation circuit is configured for applying cancellation signals to the receiver which are generated in a cancellation filter utilizing a primary impulse response characteristic corresponding to the spillover, a signal to be transmitted from each transmitter in the radar system, and a range profile output from the receiver. The cancellation circuit may also include a secondary impulse response characteristic module and a dithering module to improve the sensitivity of the receiver.

Abstract: A method for facilitating robust radar detection comprises generating a radar signal in a digital domain along at least one transmission path, the radar signal comprises a number of M periodic repetitions of a code sequence with a length Lc, multiplied with a progressive phase rotation ej·π/K·n, where Lc and M are integers, K is an integer or a non-integer, and n is a discrete time index corresponding to a code rate. The method further comprises generating a process input signal in the digital domain along at least one receiving path from a digitized reflection signal corresponding to the radar signal by multiplying the digitized reflection signal with a progressive phase rotation e−j·π/K·n. In this context, K is defined such that a ratio Lc/2·K is a non-integer, and M is defined such that a ratio Lc·M/2·K is an integer.
