    Abstract: A method for detecting a transmission symbol in a multi-antenna system is provided to reduce the complexity and improve the performance. By using a received signal, a receiving stage performs the channel estimation(S101), and then confirms channel states of each transmission antenna(S102). A channel matrix and a transmission signal vector are re-arranged(S106). The QR decomposition for the re-arranged channel matrix is performed(S107). A transmission symbol is detected(S108,S109).

    Abstract: An apparatus and a method for transmitting a signal and an inverse fast Fourier transformer are provided to reduce time delay and memory usage for adding the cyclic prefix without large variation of the hardware or power consumption. A first memory(320) stores the received data and rearranges the stored data. An inverse fast Fourier transformer(330) stores a rotation factor to output the inverse fast Fourier transform output shifted as much as the cyclic prefix and performs the inverse fast Fourier transform based on the rotation factor for the data received from the first memory successively. A cyclic prefix memory(340) stores data used as the cyclic prefix among the output data of the inverse fast Fourier transformer. A multiplexer(350) generates the OFDM symbol based on the cyclic prefix and the inverse fast Fourier conversion value stored in the cyclic prefix memory.

    Abstract: An apparatus and a method for controlling power are provided to control the transmitting power of a terminal in the outside of an FLR(full loading range) by applying power concentration gain according to a distance between a base station and a terminal to a transmitting signal of a modulator. An apparatus for controlling power in a communication system comprises a power amplifier(400), a power controller(500), and a gain controller(200). The power amplifier amplifies transmitting power of a transmitting signal. The power controller controls a gain of the power amplifier using a receiving signal. The gain controller measures a distance between a transmitter transmitting the receiving signal and the apparatus for controlling power, and applies a power concentration gain according to the distance to the transmitting signal.
