Patent ID: 7023831

Claim:
A CDMA mobile communications apparatus having a function of detecting a plurality of base stations which are possible direct connection partners by synchronizing each of the base stations at slot timing and frame timing in this order by stepwise detecting a physical channel for constant transmission from the base station, and by identifying a Scrambling Code used in the base station, comprising: a first selection unit that selects between noise and a significant slot timing for a peak correlation value at which the slot timing synchronization is performed for each of the plurality of base stations; and a second selection unit that selects a relatively large correlation value and a relatively small correlation value for the selected significant slot timings selected by the first selection unit, wherein said relatively large correlation value and said relatively small correlation value are appropriately selected at an optimal ratio to synchronize the frame timing and identify the Scrambling Code used in a base station, and wherein the relatively large correlation value and the relatively small correlation value are alternately selected to synchronize the frame timings and identify the Scrambling Codes of the plurality of base stations, respectively.
