Publication number: 20240404273Abstract: 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.Type: ApplicationFiled: August 6, 2024Publication date: December 5, 2024Inventors: Ruoyu Feng, Andre Bourdoux, Hichem Sahli, Sofie Pollin

Patent number: 8861656Abstract: A digital front-end circuit is disclosed. In one aspect, the circuit includes a filtering block for filtering received data. The filtering block has a first filter branch for filtering the received data in a first frequency band and a second filter branch for filtering the received data in a selected second frequency band. The second filter branch is in parallel with the first filter branch, is programmable and includes a block for resampling the received data. The front-end circuit also includes a circuit for performing synchronization and spectrum sensing on the received data, which is in connection with the output of the filtering block. The front-end circuit also includes a controller block for controlling the filtering block and the synchronization circuit.Type: GrantFiled: July 31, 2012Date of Patent: October 14, 2014Assignee: IMECInventors: Lieven Hollevoet, Frederik Naessens, Praveen Raghavan, Sofie Pollin, Eduardo Lopez Estraviz

Patent number: 8488626Abstract: Presented is a method of managing the operation of a system including a processing subsystem configured to run a multimedia application and a telecommunication subsystem. The method includes determining telecom environment conditions, and selecting a working point from a plurality of predetermined working points. The selecting is based at least in part on the determined environmental conditions. The method also includes setting control parameters in the multimedia application and/or the telecommunication subsystem to configure the system to operate at the selected working point, and operating the system at the selected working point.Type: GrantFiled: February 17, 2011Date of Patent: July 16, 2013Assignee: IMECInventors: Sofie Pollin, Bruno Bougard, Gregory Lenoir, Francky Catthoor

Patent number: 8228952Abstract: Disclosed is a method for managing the operation of a telecom system, and minimizing the energy to be drained from a power supply. According to the method, a rate constraint and telecom environment conditions are determined. Then, a working point is selected a plurality of predetermined working points based on the rate constraint and the telecom environment conditions. The telecom system is operated at the selected working point by setting corresponding control parameters.Type: GrantFiled: August 20, 2004Date of Patent: July 24, 2012Assignee: IMECInventors: Sofie Pollin, Bruno Bougard, Gregory Lenoir, Francky Catthoor
