    摘要： Methods and apparatus are provided for performing a handover from a macro base station to a home node in the macro base station of a mobile communications system. A location of a terminal is received from the terminal at the macro base station. A handover from the macro base station to the home node to which the terminal is registered is initiated, when a distance between the location of the terminal and a location of the home node is less than a first predefined threshold. A request for an allocation of frequency and resources having a minimum interference with the macro base station for the home node is transmitted to a home node controller.

    摘要： An apparatus and a method for interference cancellation in a Multiple Input Multiple Output (MIMO) wireless communication system. The method for interference cancellation includes equalizing first reception signals received through two or more reception antennas to estimate transmission signals transmitted through two or more transmission antennas, generating two or more second reception signals in which a mutual interference between the transmission signals is removed from the first reception signals by using the estimated transmission signals, independently equalizing the generated two or more second reception signals, and combining the independently equalized two or more second reception signals to estimate a transmission signal in which an interference is removed.

    摘要： An apparatus and a method for improving performance of an equalizer in a wireless communication system are provided. The apparatus of a reception end includes a search unit and an estimator. The search unit determines power values of respective taps inside a window based on a signal received via a pilot channel, and classifies the taps into one or more meaningful taps and one or more noise taps. The estimator allocates one or more 1-tap channel estimators to the one or more meaningful taps, and determines a channel estimation vector based on a channel estimation value of the one or more meaningful taps determined by the one or more 1-tap channel estimators.

    摘要： An apparatus and method of receiving multi-path signals in a direct sequence Code Division Multiple Access (CDMA) mobile communication system is disclosed. Timing control signals from respective fingers are collected, and relations among positions of time delays where the respective fingers intend to perform a demodulation are analyzed. If it is determined that the time delay position for a specified finger approaches the time delay position of the finger allocated with an adjacent multi-path as close as a threshold value, the distance between the time delay positions is compulsorily kept as the threshold value. This can be effected by making the timing control signal of the finger allocated with the adjacent multi-path be equally used in the specified finger.
