A method of operating a transmitting MS for establishing the P2P connection between the MSs in the wireless communication system includes when a location of a receiving MS is not known, requesting a Base Station (BS) to transmit a message instructing MSs to prepare for P2P setup, and thereafter, broadcasting to neighbor MSs a message requesting P2P-related information, receiving the P2P-related information from each of the neighbor MSs, generating a list of MSs capable of P2P communication using the received P2P-related information, and establishing a P2P connection by selecting the receiving MS from the list of MSs with which P2P communication is desired. Accordingly, in an environment where the location of the receiving MS is not known, the receiving MS can be found and thus the P2P connection can be established. Therefore, subscribers of P2P communication can be easily managed by the BS.

摘要： A method and an apparatus for transmitting a signal in a communication system are provided. An information vector is encoded according to a Low Density Parity Check (LDPC) encoding scheme, thereby generating an LDPC codeword. Minimum surviving check nodes are reserved for recovery of punctured nodes in the LDPC codeword. A check node is selected having a smallest cost function from among unreserved check nodes. A variable node is selected being unpunctured and having a smallest cost function from among variable nodes connected to the selected check node. The selected variable node is punctured when the selected variable node is not connected to the reserved check node. A stopping set check is performed when the selected variable node is connected to the reserved check node. The variable node is punctured when the stopping set check has been successfully performed. The check node is selected until there remains no variable node to be punctured and puncturing the variable node.

摘要： A differential STBC transmitting/receiving apparatus in a multiple antenna system using eight or less transmit antennas is provided. In the differential STBC transmitting apparatus, a symbol mapper receives binary data and generates a number of symbols from the binary data, each symbol having a number of bits. A space-time block encoder generates an STBC by encoding the symbols. A differential processor differentially encodes the STBC through feedback and delay. A distribution matrix processor substitutes the differentially coded STBC into a distribution matrix preset according to the number of transmit antennas, and outputs the differential STBC code of the distribution matrix to the transmit antennas.
