摘要： A scheduling technique for wireless multihop relay communication systems is provided. With spatial separation caused by the shadowing effect of surrounding buildings, a base station and its relay stations in a single cell are divided into several groups by following the rule that stations with severe potential interference are separated into different groups. The base station arranges the scheduling of these groups and serves these groups sequentially in the time domain. To take advantage of shadow effect, the same radio resources can be scheduled for relay stations within the same group due to the isolation of interfering signals. In the present invention, base stations and relay stations are equipped with directional antennas or sector antennas to further exploit the advantage of spatial separations. Different relay groups can also reuse the radio resource through appropriate power control. The cell capacity can be enhanced substantially because of aggressive radio resource reuse.

摘要： A kind of folding systolic array architecture for a CFRS decoding circuit that applies to a cell search in a wideband code division multiple access system. The invention involves using a systolic array for its decoding circuit and using a kind of folding technology to reduce the area of the systolic array. The systolic array for the decoding circuit comprises an input pattern generator, a processing element array designed in the form of a systolic array and a boundary processing element array. Given the skewed-form output results required by the systolic array and generated by the input pattern generator, the processing element array makes a set of correlating comparisons, and outputs the results of the correlating comparisons to the boundary processing elements, so as to acquire the decoding results required by the CFRS decoding. The results indicate the frame boundary and scrambling code groups of the cell search in a wideband code division multiple access system.
