Patent number: 10044388Abstract: A method is disclosed of a communication device adapted to process a received signal using either of a first channel selection filter and a second channel selection filter, where the received signal comprises signal entities each representing an individually processed block of data. The method comprises (during use of the first channel selection filter) detecting a presence of an interference signal outside a pass band of the first channel selection filter and switching to use of the second channel selection filter in response to detecting the presence of the interference signal. The method also comprises (if the switching occurs at a first point in time within a first signal entity dividing the first signal entity into a first part and a second part) applying a time domain compensation filter to one of the first part and the second part of the first signal entity. Corresponding computer program product, receiver arrangement and communication device are also disclosed.Type: GrantFiled: March 3, 2015Date of Patent: August 7, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Leif Wilhelmsson, Dzevdan Kapetanovic, Michal Stala

Patent number: 9692553Abstract: The present invention relates to a device and method of decoding code blocks of a transport block of a communication signal using a decoder. The method comprises making an assumption about how many decoder iterations should be used for different code blocks of the code blocks of the transport block, wherein the assumption is made based on a study of code block soft-bits. The method also comprises decoding the transport block using different numbers of decoder iterations for the different code blocks, based on the made assumption about how many decoder iterations should be used for the different code blocks.Type: GrantFiled: October 2, 2012Date of Patent: June 27, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jaroslaw Niewczas, Michal Stala

Patent number: 8594212Abstract: An arrangement for processing a received wireless communication signal is disclosed. The arrangement comprises a frequency offset compensation unit adapted to apply a frequency offset compensation to the received wireless communication signal, determination circuitry adapted to determine one or more adjustment values associated with the frequency offset compensation, and an FFT-unit adapted to transform the frequency offset compensated received signal to a frequency domain. The arrangement also comprises an IQ-imbalance estimator adapted to estimate an IQ-imbalance, and an IQ-imbalance compensation unit adapted to perform IQ-imbalance compensation of the received wireless communication signal based on the estimated IQ-imbalance. At least one of the IQ-imbalance estimator and the IQ-imbalance compensation unit is adapted to base its operation on the one or more adjustment values. Corresponding method and computer program product are also disclosed.Type: GrantFiled: June 30, 2008Date of Patent: November 26, 2013Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Niklas Andgart, Michal Stala

Patent number: 8538713Abstract: Re-sampling of a signal represented by a plurality of input samples is described. An output sample value is calculated for a desired time instant, tD, between any two time instants of the input samples by performing a procedure that comprises selecting a current set of values from the input sample values. A new set of values is calculated by up-sampling the current set of values. A subset of values is selected from the calculated new set of values and the current set of values surrounding the desired time instant of the output sample value, whereupon the output sample value is calculated using at least one value of the selected subset of values. The calculation of a new set of values and the selection of a subset of values from the new set and the current set is iterated a specific number of times, wherein during the iteration the current set of values is set to the selected subset of values.Type: GrantFiled: December 10, 2010Date of Patent: September 17, 2013Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Can Bilgin, Rakesh Gangarajaiah, Michal Stala

Publication number: 20080266083Abstract: A system, method and computer application for electronic device 10 for detecting movement near an electronic device. The electronic device includes movement detection circuitry configured to detect movement of an object near the movement detection circuitry. The movement detection circuitry includes at least one sensor that detects movement and generates at least one output signal corresponding to a position of the object detected. The electronic device further includes a memory for storing one or more predefined state parameters that correspond to one or more predefined movements to be detected by the movement detection circuitry. During processing, the output signals of the sensors are processed by averaging signals received from the one or more sensors to determine vertical movement above the movement detection circuitry and a determination is made as to whether the output signals of the one or more sensors are active or inactive to determine horizontal movement across the movement detection circuitry.Type: ApplicationFiled: November 9, 2007Publication date: October 30, 2008Applicant: SONY ERICSSON MOBILE COMMUNICATIONS ABInventors: Magnus Midholt, Michal Stala
