    摘要: Provided is an apparatus and method for simultaneously receiving data signals of two adjacent frequency allocation (FA) in a cellular environment. When there is another base station using an adjacent FA to an FA of the base station, a subcarrier mapper maps control information to subcarriers of predetermined sections such that a mobile station simultaneously receives data signals of the adjacent FAs. An inverse fast Fourier transform (IFFT) processor IFFT-processes data mapped to the subcarriers. Because two different BSs transmit the same data through independent paths, the mobile station can obtain a macro diversity gain. Also, it is possible to balance the loads of the two BSs.

    摘要: Apparatus and method for simultaneously selecting two cells in a broadband cellular communication system with a frequency reuse factor of N. Adjacent cells are searched and the RX power strengths of the adjacent cells are measured. Cells with RX power strengths greater than a predetermined value are selected among the adjacent cells. Two cells are selected among the selected cells and the FAs and RX power strengths of the two cells are compared. If the two cells have adjacent FAs and/or similar RX power strengths, the two cell are selected to perform communication. The apparatus and method simultaneously receives data signals from two cells with adjacent FAs in a cellular environment with a frequency reuse factor of N, by sharing the adjacent FAs.

    摘要: A symbol demapping method and apparatus for efficient interference cancellation in a wireless communication system. Decision signal points are generated which include decision signal points based on a modulation scheme and a virtual signal point added to a zero point. A magnitude of a complex value of an input signal is compared with a threshold based on system setting. When the magnitude of the complex value is less than the threshold, the virtual signal point of the zero point is mapped and output as a target decision signal point. When the magnitude of the complex value is greater than or equal to the threshold, one of the decision signal points based on the modulation scheme is mapped and output according to the com0plex value.
