摘要： An apparatus and method for improving the performance of an error correction code against the effects of error waves in a Multi-Input Multi-Output (MIMO) communication system are provided. In a receiver of the MIMO communication system, a Minimum Mean Square Error (MMSE) receiver unit estimates transmitted signals from at least two paths using signals received at each of receive antennas, a signal deprocessor selects one of the estimated signals, stores the other estimated signal, assigns weighting values to the selected signal and a previous detected signal, combines the weighted signals, and detects transmitted data from the combined signal, a signal reproducer reproduces a transmitted signal from the detected transmitted data, and a subtractor updates the received signals by subtracting the reproduced transmitted signal from the received signals and provides them to the MMSE receiver unit.

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.

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.
