|20090215390||METHOD AND APPARATUS FOR ESTIMATING/REMOVING ECHO SIGNAL USING CHANNEL COEFFICIENT PREDICTING TECHNIQUE IN MULTI-CARRIER SYSTEM - A method and an apparatus are provided for estimating and removing interference of a signal at a wireless repeater operating in a multi-carrier system. In the method, a current echo channel linear prediction coefficient, which represents a coefficient between a current train signal section and a previous train signal section, is estimated using a current echo channel coefficient estimated in the current train signal section and a previous echo channel coefficient generated in the previous train signal section. A next echo channel coefficient is estimated using the current echo channel coefficient, the previous echo channel coefficient, and the current echo channel linear prediction coefficient. An echo channel coefficient outside a train signal section is estimated using the current echo channel coefficient and the next echo channel coefficient.||08-27-2009|
|20090180468||Universal plug and play method and apparatus to provide remote access service - Disclosed are a universal plug and play (UPnP) method and a UPnP apparatus providing remote access service. The method includes receiving external inputs of an identifier of a remote access server (RAS) to generate a credential and a session initiation protocol (SIP) identifier of the RAS, generating a payload of a SIP packet including a credential identifier (ID) generated based on the identifier of the RAS, remote access transport agent (RATA) capability information, and a transport address (TA) set corresponding to candidate IP addresses to access a remote access client (RAC), and transmitting the SIP packet to the RAS.||07-16-2009|
