    摘要： Disclosed is a space-time coding apparatus and method to flexibly adjust diversity/multiplexing orders in a multiple-antenna system. The transmitting apparatus for the multiple-antenna system includes a space-time code controller, an encoder, a demultiplexer, and a space-time encoder. The space-time code controller generates space-time codes by determining bases according to a multiplexing order required by a receiver. The encoder modulates and encodes data destined for the receiver in accordance with a predetermined modulation level. The demultiplexer demultiplexes data received from the encoder in order to transmit the data through at least one antenna. The space-time encoder space-time-codes the demultiplexed data using the space-time codes.

    摘要： An apparatus and method for removing interference in a transmitting end of a multi-antenna system is provided. The method includes decomposing a channel matrix comprising channel coefficients for a plurality of terminals, calculating a value proportional to an interference signal for each of antennas, and calculating a sum of a transmission signal and the calculated value for each terminal and multiplying the calculated sum by the decomposed channel matrix. Accordingly, channel capacity can be improved by optimizing a data transfer rate and transmission power for each terminal.

    摘要： A system and method are provided for controlling a data rate in a communication system. A transmitter sets threshold values for classifying Modulation and Coding Scheme (MCS) levels. When receiving information about an MCS level desired to be used in the receiver, the transmitter sets an MCS level to be actually used in the receiver and transmits information about the set MCS level to the receiver. When detecting that the information is to be transmitted to the transmitter, the receiver computes instantaneous link capacity using a channel estimation result, sets an MCS level mapped to the instantaneous link capacity, and transmits information about the set MCS level to the transmitter. The receiver receives the information about the MCS level to be actually used from the transmitter.
