The transformation of the first messages into second messages comprises the application of an orthogonal transformation by means of vectors obtained from rows or columns of an identity matrix.Type: ApplicationFiled: November 29, 2010Publication date: December 1, 2011Applicants: ST-ERICSSON SA, ST-ERICSSON (GRENOBLE) SASInventor: Abdelaziz Goulahsen

Publication number: 20110292785Abstract: Methods and apparatus for distributing content using a spectrum generation device. In one embodiment, digital content is received via a time-multiplexed network transport (such as Gigabit Ethernet), and converted to frequency channels suitable for transmission over a content distribution (e.g., Hybrid Fiber Coaxial (HFC)) network. In one variant, the conversion is performed using digital domain processing performed by a full spectrum generation device. Additionally, methods and apparatus for selectively adding, removing, and/or changing digital content from the full spectrum device are also disclosed. Various aspects of the present invention enable physical (infrastructure) consolidation, and software-implemented remote management of content distribution.Type: ApplicationFiled: May 27, 2010Publication date: December 1, 2011Inventor: Glen Hardin

Publication number: 20110292786Abstract: A method and apparatus are provided for synchronizing a terminal with a frequency from an ordered initial sequence of frequencies of a radio-communications network. An available power spectrum associates to each frequency of the initial sequence a power value representing the power with which the frequency is received by the terminal. At least one first range of consecutive frequencies is determined within the initial sequence, having a power variation below a first predetermined threshold. The terminal attempts at least one first synchronization with a frequency of the first range. If each first synchronization fails, the terminal obtains a modified sequence by modifying the position of the frequency or frequencies of the at least one first range of the initial sequence or by eliminating the at least one first range. The terminal then attempts a second synchronization with at least one of the frequencies of the modified sequence.Type: ApplicationFiled: May 27, 2011Publication date: December 1, 2011Applicant: SIERRA WIRELESSInventors: Ludovic Haessler, Christophe Fléchelle

Publication number: 20110292789Abstract: A method, apparatus and system for Ethernet Ring Protection (ERP) are disclosed. The method includes: detecting, by a node, a link fault on a ring; blocking, by the node, a port connected with the faulty link after detecting the link fault, and sending a fault alarm message to other nodes on the ring, wherein the fault alarm message contains a fault identifier; and judging, by a node which receives the fault alarm message, whether the fault identifier changes; if the fault identifier changes, the node which receives the fault alarm message storing the fault identifier contained in the fault alarm message and clearing a forwarding table of the node which receives the fault alarm message.Type: ApplicationFiled: August 10, 2011Publication date: December 1, 2011Inventors: Hao LONG, Yang Yang
