The method and apparatus uses the uplink quality indication channel for determining the downlink channel response, or uses round trip pilot relay channel sounding. The uplink quality indication channel may comprise modified... Agent: Dinsmore & Shohl LLP

20080095224 - Semiconductor integrated circuit: A semiconductor integrated circuit has first and second delay circuits that have n (n is an integer equal to or larger than 2) delay elements connected in series, respectively, and in which an identical input signal is inputted to delay elements at a first stage and output signals of delay... Agent: Amin, Turocy & Calvin, LLP

20080095225 - System, multi-stage equalizer and equalization method: A system, a multi-stage equalizer and a method for generating an equalized signal in response to a received signal are provided. The multi-stage equalizer comprises a first DFE, and a second DFE. The first DFE generates a first signal in response to the received signal. The second DFE generates a... Agent: Grossman, Tucker, Perreault & Pfleger, PLLC

20080095226 - Apparatus for phase noise suppression for ofdm based wlans: Orthogonal frequency division multiplexing (OFDM) has been specified by IEEE 802.11a standard as the transmission technique for high-rate wireless local area networks (WLANs). Performance of an OFDM system, however, is heavily degraded by random Wiener phase noise, which causes both common phase error (CPE) and inter-carrier interference (ICI). A method... Agent: Connolly Bove Lodge & Hutz LLP

20080095228 - System and method for providing picture output indications in video coding: An explicit signaling element for controlling decoded picture output and applications when picture output is not desired. A signal element, such as a syntax element in a coded video bitstream, is used to indicate (1) whether a certain decoded picture is output; (2) whether a certain set of pictures are... Agent: Foley & Lardner LLP

20080095227 - Method and apparatus of sharing interactive application: The present invention provides a method for generating a digital program having at least one interactive application, said interactive application is based of at least one data object, said method comprises: first, receiving setting on the sharing characteristic of said data object, then generating a corresponding interactive application according to...
