摘要： Provided are a transmitter and a method for transmitting a data block in a wireless communication system. The method comprises the following steps: encoding an information bit and generating a block coded with an NCBPSS bit; generating two sub-blocks by parsing the coded block; and transmitting the two sub-blocks to the transmitter. By preventing the bits that are contiguous to the encoding block from having continuous identical reliabilities on a signal constellation, the deterioration of the decoding performance of the transmitter can be prevented.

摘要： Provided is a transmitter and a receiver for a high-throughput wireless communication system. The transmitter includes a baseband transmitter, a DIF transmitter, and a RF transmitter. The baseband transmitter performs a MAC protocol process on transmission signals and reception signals and processes the transmission signals by dividing an entire transmission band into n bands in a physical layer process of the transmission data, where n is a natural number. The DIF transmitter combines transmission signals of each band from the baseband transmitter and outputs m channel signals corresponding to a number of transmission antennas, where m is a natural number. The RF transmitter modulates each of the channel signals transferred from the DIF transmitter and transmits the modulated signals through m antennas.

摘要： A transmitting apparatus and receiving apparatus of a multi-carrier system using multiple antennas is proposed. An LCF encoder (202) of the transmitting apparatus performs a liner precoding to input signals to be transmitted to a receiving apparatus using a liner complex matrix considering the number of multiple antennas and the number of subcarriers, and a subcarrier allocator (203) respectively allocates a subcarrier to the signals liner-precoded by the LCF encoder. A transmitter (205) respectively transmits the signals having a subcarrier allocated by the subcarrier allocator through the multiple antennas externally. A subcarrier de-allocator (208) of a receiving apparatus extracts a liner-precoded signal by de-allocating a subcarrier allocated to the received signal. An LCF decoder (209) outputs a bit reliability of the received signal to the liner-precoded signal extracted from the subcarrier de-allocator considering the number m of multiple antennas and the number n of subcarriers. A performance may be improved by using space diversity due to multiple antennas and a frequency diversity due to the OFDMA system and a complexity may be reduced and a hard decision value of a performance similar to the maximum likehood detection may be obtained by using a lattice reduction and a 2-branch Chase decoder.

摘要： Disclosed is a method for constructing a downlink frame in a mobile data communication system using an OFDMA method. To construct the downlink frame, a single preamble is arranged at the head of the downlink frame, and a plurality of data symbols are arranged following the preamble. Then, a plurality of pilot symbols are inserted between the data symbols over the downlink frame at a predetermined period. Accordingly, a channel variation can be rapidly tracked using the preamble and pilot symbols. Furthermore, interference between adjacent cells is minimized and averaged to make a frequency reuse rate be 1, such that arrangement of multiple cells can be easily designed.

摘要： Respective codewords of quantization codebooks corresponding to a number of data streams are selected based on channel information estimated by a received training symbol. A stream mode is selected among stream modes to determine a modulation method applied to each data stream. The data stream is detected by using the codeword corresponding to the quantization codebook of the data stream corresponding to the selected stream mode as a precode matrix, and the detected data stream is modulated. In this case, a receiving apparatus (120) performs a feedback operation so that indexes of the selected stream mode and the codeword used as the precode matrix may be transmitted to the apparatus (110). The transmitting apparatus selects the number of transmitted data streams and the modulation method based on the transmitted index of feedback streams by the feedback operation.

摘要： Disclosed is a method for configuring an uplink frame in an OFDMA based wireless communication system. The total band of the uplink frame is divided into a predetermined number of subcarrier groups. Subcarriers within the respective allocated subcarrier groups are allocated to the subchannel defined for a predetermined number of consecutive symbols defined by slots in the uplink frame. Pilot subcarriers are allocated by the unit of the predetermined number of symbols so as to allow channel estimation from among the allocated subcarriers. Accordingly, data subcarriers are allocated by minimizing collision with specific users of adjacent cells so as to enable channel estimation using preambles in a cellular system, and some positions of the data subcarriers are allocated for pilots, thereby allowing synchronous demodulation and improving frequency reuse rates.
