  • Patent number: 8457239
    Abstract: The method is for managing operation of a first apparatus belonging to a first communication system and exchanging within the first communication system a multi-carrier modulated signal on several sub-carriers. The method includes detecting at the first apparatus the presence of an interfering signal emitted from a victim apparatus on a sub-carrier. The method may also include determining at the first apparatus the path loss between both apparatuses, determining from the path loss and from an allowed interference level at the victim apparatus a maximum allowed transmit power on the sub-carrier of a multi-carrier modulated signal to be transmitted from the first apparatus, and adjusting within the first apparatus the processing of the multi-carrier modulated signal to be transmitted in accordance with the maximum allowed transmit power.

  • Patent number: 8341507
    Abstract: A method of decoding a received systematic code encoded block corresponding to an original block of information, wherein the received systematic code encoded block may include soft systematic values, may include detecting an error condition in the received systematic code encoded block. The method may also include decoding the received systematic code encoded block for retrieving the original block of information if the error condition in the received systematic code encoded block is detected and processing the soft systematic values to retrieve the original block of information instead of the decoding if the error condition in the received systematic code encoded block is not detected.

  • Patent number: 8259879
    Abstract: The method is for detecting the eventual presence of an interferer that is adapted to interfere with a wireless device. The wireless device is provided with at least one receiving chain including an analog to digital conversion stage. The method includes receiving on the receiving chain an incident signal, and delivering to the ADC stage an analog signal from the incident signal. The method further includes elaborating or determining a binary information from a binary signal delivered by the ADC stage and representative of the level of the analog signal, analyzing a temporal evolution of the binary information and detecting the presence of the interferer from the analysis.

  • Patent number: 8238495
    Abstract: A method includes a main interference reduction mode for reducing the interference generated by a wideband device toward a narrowband device. The main interference reduction mode is performed within the wideband device and includes at least one of detecting an emission from and a reception performed by the narrowband device. A group of at least one sub-carrier having frequencies interfering with frequencies used by the narrowband device is determined from the detection step. The bits of the punctured stream that correspond to the information carried by the interfering sub-carriers of the group are determined and processed so that the processed bits are mapped into a reference symbol having an amplitude within a threshold of zero.

  • Patent number: 7836376
    Abstract: To control a decoding latency, larger blocks are nonequally segmented into smaller ones. The decoding process starts directly after reception of the first small block. The latency is defined by the latency of the last small block decoding. Changing the number of iterations during the turbo-code decoding also permits control of the decoding latency.
