    摘要： A sphere decoder sets a Euclidean distance between a lattice vector obtained by using an MMSE or ZF estimate and a received signal as an initial radius, further reduces the initial radius, and searches lattices points included inside a hypersphere with the further reduced initial radius. In addition, one lattice vector having a minimum Euclidean distance is output. One dimension is selected to reduce an initial radius, and estimates in other dimensions are kept fixed, excluding the selected dimension. Then candidate lattice points are searched in the selected dimension, excluding a current estimate, such that a minimum Euclidean distance and a lattice point estimate corresponding to the minimum Euclidean distance are obtained. The initial radius is updated by the minimum Euclidean distance, and a final lattice vector is constructed by combining a lattice point estimate corresponding to the initial radius and the lattice point estimates in other dimensions.

    摘要： A multicell communication system includes a plurality of cells which use a frequency band on a division basis, wherein a frequency reuse factor K is defined such that the frequency band is divided into K sub-frequency bands, the K sub-frequency bands are allocated to K cells including a serving cell among the plurality of cells, and the K sub-frequency bands are reused in some of the remaining cells other than the K cells, and the K cells use the frequency band on a division basis. The frequency band is divided into a plurality of segment bands. The plurality of segment bands is mapped such that at least one of the segment bands is allocated to each of the band groups, to divide the frequency band into the K band groups. The K band groups is mapped such that a first band group which is a particular one of the K band groups is allocated to a center band, and the K band groups are mapped such that the remaining band groups other than the first band group among the K band groups are allocated to reuse band groups.
