Abstract: A Bose-Chaudhuri-Hocquenghem(BCH) error correction method using an error correction encoder for checking error and a circuit for the method are provided to reduce power consumption and time for error correction by performing BCH error correction more simply. A Bose-Chaudhuri-Hocquenghem(BCH) error correction circuit comprises an error correction encoder(1120) and an error correction unit(1140). The error correction encoder generates first parity data by receiving normal data to be written in a memory cell array(1160) and writes the normal data and the first parity data into the memory cell array. The error correction unit corrects error of the normal data written in the memory cell array in response to an error signal. The error correction encoder transmits the error signal to the error correction unit when the normal data has error. The error correction encoder comprises an encoding part generating the first and second parity data, a comparison part comparing the first parity data with the second parity data and a check part checking error in response to the comparison result.

Abstract: An SDMA(Space Division Multiple Access) multi-user wireless communication system and a method for the same are provided to reduce the volume of necessary information to report a beamforming vector to a mobile station without a decrease in power efficiency. An SDMA multi-user wireless communication system comprises a base station and a mobile station. The base station creates a difference beamforming vector, and transmits an individual pilot through the difference beamforming vector. The mobile terminal receives the individual pilot transmitted through the difference beamforming vector, creates a beamforming vector, and calculates an effective channel on the basis of the created beamforming vector. The difference beamforming vector is equivalent to the difference between the beamforming vector and the mobile station's channel vector. The mobile station multiplies the beamforming vector by the channel vector and obtains the effective channel.

Abstract: A method for dynamically allocating channels in a multi-cell downlink system is provided to increase performance about throughput per unit area as compared to other channel allocation techniques by allocating a channel in consideration of a mobile terminal's interference range dependent on the distance between a base station and the mobile terminal. A base station, if a channel allocation request is detected, checks whether unassigned channels exist(600,602). If unassigned channels exist, the base station selects one of the unassigned channels(604). On the assumption that the selected channel is allocated, the base station judges whether the selected channel has influence on mobile terminals which belong to neighbor base stations(606). In case it is judged that any of the mobile terminals which belong to neighbor base stations is not influenced by the selected channel, the base station allocates the selected channel(610). Then the base station transmits downlink channel allocation information to the neighbor base stations, including allocated channel information(612).

Abstract: A point-to-multipoint file transmission method in a CPM(Converged IP Messaging) system is provided to improve the performance and reliability of file transmission in transmitting files in a CPM system by transmitting a list of file receivers to a server, entrusting the server with file transmission management, and transmitting a file under the management of the server. In order to transmit a file to a plurality of receiving terminals, a sending terminal transmits a receiver list to a server in charge of the sending terminal(S210). Receiving the receiver list, the serve rin charge of the sending terminal verifies whether the sending terminal is capable of file transmission(S220). If so, the server in charge of the sending terminal asks each server in charge of each of the receiving terminals whether to be willing to receive the file(S230). Each server in charge of each receiving terminal verifies whether each receiving terminal is capable of file reception(S240). In case a server in charge of a receiving terminal judges that the receiving terminal is capable of file reception, the server asks the receiving terminal whether to be willing to receive the file(S250). The servers in charge of the receiving terminals respectively receive reception consent or denial responses from the receiving terminals and transmit the received responses to the server in charge of the sending terminal(S260). Based on the reception consent/denial responses, the server in charge of the sending terminal creates a new receiver list(S270).
