Abstract: An apparatus and a method of recovering a frequency in an OFDM(Orthogonal Frequency Division Multiple) system are provided to reduce a convergence speed during a process of recovering a fine carrier frequency by adaptively compensating an initial subcarrier frequency offset value when the FFO is approximately 0.5. A method of recovering a frequency in an OFDM system includes the steps of: operating an autocorrelation value between a receiving signal and an advance appointed symbol(701); detecting at least the largest three values among the operated autocorrelation values(703); estimating and compensating a part of an IFO(Integer Frequency Offset) of subcarrier spacing, and an FFO(Fractional Frequency Offset) of the subcarrier spacing by using the detected autocorrelation values; and performing synchronization of a fine carrier frequency to compensate the remaining carrier frequency offset after performing the compensation of the frequency offset through the previous step(717).

Title: Method and system for peer-to-peer authorization
Inventor: WARDROP PATRICK R
IPC: G06F17/30
Filed: 2003-11-14
Abstract: An authorization mechanism within a peer- to-peer network is presented. A central server that operates a centralized data repository search engine within a peer-to-peer network performs authentication and authorization operations with respect to users that access its services. A user at a peer node reviews peer-to- peer search results that have been gathered and returned by the centralized search engine. When the user desires to retrieve a file from another peer node, the user's peer node must obtain an authorization token from the central server, which authenticates the user or has previously authenticated the user. The user's peer node then presents the authorization token along with a request to retrieve the file from the other peer node. After verifying the authorization token, the other peer node responds with the requested file. If the other peer node cannot verify the authorization token then the other peer node denies access to the file.
