Abstract: A method and an apparatus for managing peers in a P2P network system are provided to increase the overall processing and response speed of a P2P network system by acting as a substitute for a super peer so as to reduce the loading of the super peer. A peer management apparatus(312) consists of a first interface part(10), a second interface part(20), a packet detection part(30), a packet management part(40), a storage part(60), and a packet transfer part(50). The first interface part controls the packet transmission paths between internal peers and the second interface part. The second interface part executes packet forwarding between the first network device(311) and the first interface part. The packet detection part detects and acquires it if a packet is transmitted or received through the first interface part or the second interface part. Analyzing the acquired packet, the packet management part confirms the second peer or a peer group which the first peer tries to access or extracts information about the first peer, the second peer or the peer group. The storage part stores peer or peer group information, extracted through the packet management part, according to peers or groups. The packet transfer part, if information corresponding to the second peer or a peer group which the packet management part confirms exists in the storage part, creates a packet having the corresponding information and delivers it to the first peer.

Abstract: Channel equalization and carrier recovery methods and a receiver in a high-speed wireless communication system are provided to apply a single-carrier transmission scheme with a simple structure and low power consumption in an interior environment in which channel distortion by multiple paths is extreme, thereby performing high rate data communication. Channel equalization and carrier recovery methods in a high-speed wireless communication system comprise the following steps of: acquiring the initial value of a channel equalization coefficient through non-casual channel estimation in a frequency domain during the preamble transmission section of a packet(400); performing the compensation of a QAM(Quadrature Amplitude Modulation) signal for updating the channel equalization coefficient in a temporal domain during the data transmission section of the packet(410); and compensating a carrier phase error by determining channel equalization coefficient tracking based on the determination of the frequency domain and a compensation value based on the compensation of the QAM signal if a payload section begins in the data transmission section of the packet, and updating the channel equalization coefficient(420,430).

Abstract: An apparatus and a method for detecting a preamble packet in an OFDM(Orthogonal Frequency-Division Multiplexing) system are provided to improve the accuracy of detecting the preamble packet even in case that an interference signal exists or received signal power is small. An apparatus for detecting a preamble packet in an OFDM system includes a cross-correlation calculating unit(21), a delay unit(22), a power measuring unit(23), and a dividing unit(24). The cross-correlation calculating unit calculates the cross-correlation value with the stored preamble pattern value for an OFDM symbol(N-point) period according to the reception of a signal. The delay unit delays the cross-correlation value calculated in the cross-correlation calculating unit as much as a protection(M-point) period. The power measuring unit measures the received power for the protection period. The dividing unit divides the cross-correlation value delayed in the delay unit by the power value measured in the power measuring unit to calculate the final cross-correlation value.
