摘要： A transmitting apparatus and receiving apparatus of a multi-carrier system using multiple antennas is proposed. A linear complex field (LCF) encoder performs linear precoding of input signals to be transmitted using a linear complex matrix based on the number of antennas and the number of subcarriers, and a subcarrier allocator allocates a subcarrier to each precoded signal. A transmitter transmits the signals through the multiple antennas. In a receiving apparatus, a subcarrier de-allocator extracts a linear-precoded signal by de-allocating a subcarrier of the received signal, and an LCF decoder outputs a bit reliability of the received signal based on the number m of antennas and the number n of subcarriers. Performance may be improved by using space diversity using multiple antennas and frequency diversity using OFDMA, and system complexity may be reduced by using a lattice reduction and a 2-branch Chase decoder.

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 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 transmitting apparatus. 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 allocating data and pilots, a transmitting method and device, a receiving method and device in an OFDMA system. A terminal partitions subcarrier groups and symbols from an uplink channel based on a basic pilot pattern generated by a specific reference, receives at least one subchannel based on the partitioned subcarrier groups and symbols, hops the subcarrier groups caused by the subchannel according to hopping patterns, allocates data, and differently positions the pilots per subcarrier group based on the basic pilot pattern. Accordingly, the probability of pilot collision between adjacent cells is reduced, and accuracy of channel estimation is increased through boosting the pilot subcarrier power.
