摘要： The present invention relates to an apparatus and a method for selection of a precoding matrix. In the present invention, a precoding matrix to enable an effective signal-to-noise ratio (ESNR) to have a maximum value with respect to a signal vector that requires retransmission is selected in a codebook and fed back to a transmitter. Accordingly, since the effective signal-to-noise ratio has the maximum value after the signal vector is retransmitted, it is possible to minimize a reception error probability of retransmission.

摘要： In an orthogonal frequency division multiple access (OFDMA) communication system, a transmission apparatus connects a plurality of tiles, which have a 4x3 structure, along a time axis or a frequency axis in an uplink 4-layer PUSC mode, and designs pilots corresponding to one layer at one of a plurality of symbol positions adjacent to a first corner of the plurality of tiles and one of a plurality of symbol positions adjacent to a second corner of the plurality of tiles that face the first corner in a diagonal direction. In this case, null symbols are designed at the rest of the symbol positions adjacent to the first corner or the second corner where the pilots are not designed. Accordingly, a receiving apparatus can obtain n channel values from n tiles. Further, n estimated channel values are applied to a linear interpolation method, so that it is possible to estimate the entire channel value of n tiles.

摘要： The present invention provides a method and an apparatus for symbol mapping. The encoder, for example a systematic encoder, of the symbol mapping apparatus encodes transmission data (S410) and outputs data in which a plurality of redundancy bits are added to a plurality of information bits. A puncturer punctures the information bits and the redundancy bits (S420). An information interleaver interleaves the punctured information bits, and a redundancy interleaver interleaves the punctured redundancy bits (S430). Finally, the symbol mapper maps the interleaved information bits and the interleaved redundancy bits onto the symbols (S440). The average log-likelihood ratio (LLR) value of mapped information bits is different from the average LLR value of the mapped redundancy bits.

摘要： Provided are a transmitting apparatus and a transmitting method in a multiple input multiple output system. A power allocation controller includes a block Tomlinson-Harashima precoder (BTHP) that precodes and outputs data to be transmitted to each user in a nonlinear scheme. The BTHP removes and outputs inference signals from data for each user based on the channel information that is fed back from the users. The data for each user output from the BTHP are allocated with power by the power allocation controller. The power allocation controller calculates power allocation parameters so that receiving minimum distances at receiving ends for each user that receive data through the MIMO antennas are the same, and allocates the calculated parameters to data for each user.

摘要： The present invention relates to a method for connecting a base station and a repeater for a spatial division multiple access, and a repeating method thereof. In order to provide efficient spatial division by using a repeater, data streams are repeated by using a repeating system including at least one repeater for performing wireless communication with a terminal located in a repeating region controlled by using at least one repeating antenna and a base station including a plurality of base station antennas corresponding to the repeating antenna. In this instance, the terminal detects location information on the repeating region to which the terminal belongs by using the pilot signal transmitted by the base station or repeated by the repeater. Location in¬ formation detected by the terminal is fed back to the base station so that the base station may use it for the spatial division multiple access for simultaneous transmission to many terminals. Therefore, the spatial division multiple access for increasing sector capacity by efficiently combining the base station including multiple antennas and the repeater is available.
