摘要： Provided is a method and apparatus for controlling a gain of a receiver in a wireless communication system. The method of controlling a gain of a received signal in a receiver using a Low Noise Amplifier (LNA) and a Variable Gain Amplifier (VGA) includes respectively generating first gain control signals for the LNA and the VGA based on a signal received via an antenna and digitized by the LNA and the VGA, measuring a power detection value from power of a low-noise-amplified signal by the LNA, determining offsets for controlling increase and decrease of the first gain control signals based on the power detection value of the LNA output, and respectively providing second gain control signals obtained by adding the offsets to the first gain control signals to the LNA and the VGA.

摘要： An apparatus and method are provided for receiving data generated by sequentially performing bit interleaving, symbol interleaving and symbol mapping in a wireless communication system. A fast Fourier transform (FFT) processor receives in-phase/quadrature phase (I/Q) data of a radio channel generated by sequentially performing bit interleaving, symbol interleaving and symbol mapping, and performs an FFT process for the I/Q data. A symbol deinterleaver performs a process for symbol deinterleaving the FFT I/Q data and reference values to be used for symbol demapping of the I/Q data and outputs the symbol-deinterleaved I/Q data and reference values. A symbol demapper performs a process for symbol demapping the symbol-deinterleaved I/Q data according to the reference values. A bit deinterleaver performs a process for bit deinterleaving the symbol-demapped data. A demultiplexer demultiplexes the bit-deinterleaved data.

摘要： A method and apparatus for canceling interference during reception of a broadcast signal in a hybrid terminal including a broadcast receiver and a mobile communication terminal. In the interference cancellation apparatus, a gain controller adjusts transmission power of the mobile communication terminal, and a transmission power controller determines whether there is a burst of a broadcast signal that the broadcast receiver will receive. If there is a burst of the broadcast signal, the transmission power controller controls the gain controller to decrease transmission power of a mobile communication signal transmitted by the mobile communication terminal at a corresponding slot.

摘要： An apparatus and method for receiving a signal in a MIMO communication system are provided. In the signal receiving method, a first received signal received at each of the receive antennas is equalized in a predetermined first method. Each of the equalized transmit antenna signals is despread with a plurality of spreading codes used in a transmitter. The strongest transmit antenna signal is detected among the despread transmit antenna signals, and decoded in a predetermined second method, for error verification. The verified strongest transmit antenna signal is reproduced as an interference signal. A second received signal is generated by subtracting the interference signal from the first received signal and equalized in the first method. The above operation is repeated on the equalized transmit antenna signals except the strongest transmit antenna signal.
