Abstract: A coherent phase enhancement spectrum detector using orthonormal tapering and a method thereof are provided to randomly increase size of a wave area by using a taper having orthonormal properties when power spectrum of a periodic signal is measured, thereby additionally obtaining noise attenuation effect. NxM data is divided into M blocks, and the divided block data are applied with an FFT(Fast(discrete) Fourier Transform) process(401). The data blocks are expanded through orthonormal tapering, and the expanded data blocks are applied with an FFT(discrete) process into ensemble areas(403,405). Signals further reacting as many as tapers are classified as signals of the same properties, and the classified signals are shuffled again(407).

Abstract: A device for improving IDD(Iterative Detection and Decoding) reception performance in a multi-antenna system and a method thereof are provided to generate an LLR(Long Likelihood Ratio) by performing sorted QR decomposition in the multi-antenna system, thereby reducing complexity without deterioration of performance of a receiving device. A detector(301) estimates a transmission signal by using a signal received through an antenna. An LLR generator(305) generates an LLR by conducting sorted QR decomposition for a signal fed back from a decoder(309) or the transmission signal estimated in the detector(301). A deinterleaver(307) performs a deinterleaving process for the generated LLR, and provides the deinterleaved LLR to the decoder(309).

Abstract: A system and a method for transmitting/receiving data in communication system are provided to reduce the ACK packet transport overhead by including only the mandatory field information to the BW-REQ message. A mobile station receives data packet from a base station(501). The mobile station inspects the ID field, the header checksum system field, and the ack_num field etc(503). The mobile station detects the difference of the ack_num field data of the ACK packet at t point and the ack_num field data of the ACK packet at (t-1) point(505). The mobile station produces the BW-REQ-ACK message including the ack_num difference field(507). The mobile station sends the BW-REQ-ACK message produced to the base station(509). The mobile station produces the BW-REQ message including the bandwidth request field(511). The mobile station sends the BW-REQ message to the base station(513).

Abstract: A control information communication device in a broadband wireless access system and a method thereof are provided to transmit a compressed control message(map message) if control information on a random CID(Connection Identifier) is the same as existing control information, thereby reducing size of the control information(map). A base station performs a resource scheduling process for the current frame(401). The base station confirms scheduling information(403), and checks whether existing scheduling information for each CID is the same as the current scheduling information(405). If so, the base station generates a compressed map message which includes CID information only for corresponding bursts(407). The base station generates and broadcasts map bursts which include map messages for the bursts(413).
