摘要:
Apparatus for classifying a ray is disclosed, wherein the ray is received at a code division multiple access receiver. The apparatus comprises: means for receiving a neighbouring cell list comprising at least information concerning scrambling codes used by, and timing information concerning at least one neighbouring cell; means for selecting a cell from the neighbouring cell list, the cell having associated therewith one or more scrambling codes; means for determining whether the number of cells in the neighbouring cell list exceeds a threshold; means responsive to a positive determination for attempting to classify the ray to the selected cell without utilising means for mixing a received signal with a scrambling code; and means responsive to a negative determination for mixing a received signal with a scrambling code used by the selected cell to provide a mixed signal, and for examining the mixed signal to determine if the ray originates from the cell.
