摘要： A gap filler apparatus providing cyclic delay diversity in a digital multimedia broadcasting (DMB) system. In the gap filler apparatus, a receiver receives an orthogonal frequency division multiplexing (OFDM) signal transmitted as a broadcasting signal. A symbol synchronization unit acquires symbol synchronization of the OFDM signal, detects a guard interval of an OFDM symbol using the symbol synchronization, determines a sample length, by which the OFDM symbol is cyclic-delayed within the guard interval, and cyclic-delays the OFDM signal by the determined sample length. An amplifier amplifies the cyclic-delayed OFDM signal. A transmitter transmits the amplified OFDM signal to a wireless network.

摘要： An optimum I/Q imbalance compensating apparatus and method in a zero-IF OFDM receiver. In the apparatus, a first compensator generates a first symbol by removing interference from a second distorted symbol on an (Ns−m+1)th subcarrier from a first distorted symbol on an mth subcarrier by a first compensation coefficient in an OFDM FFT signal of Ns subcarriers. A first hard decider generates a first compensated symbol by hard-decision on the first symbol, an error calculator generates an error symbol by subtracting the first received symbol from the first compensated symbol. A second compensator generates a second symbol by eliminating interference from the first distorted symbol from the second distorted symbol using a second compensation coefficient. A second hard decider generates a second compensated symbol by hard-decision on the second symbol, and an adaptive controller updates the first compensation coefficient using the error symbol and the second compensation symbol.

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.

摘要： A method and apparatus for efficiently transmitting channel quality information on a radio channel in a mobile communication system are provided. The reporting cycle of channel quality information is changed adaptively according to time-varying characteristics associated with the Doppler frequency of a radio channel or the variation of the channel quality information. Therefore, the channel quality information is efficiently transmitted. Also, the decrease of unnecessary frequent information transmissions reduces an uplink interference power level and power consumption in user equipment (UE), as well.
