Abstract: A spreading code synchronization circuit in a RAKE receiver in a spread-spectrum mobile communication system reassigns receiver fingers that are tracking substantially the same synchronization positions as other fingers, as well as reassigning fingers that are tracking synchronization positions with low correlation power. Under adverse multipath reception conditions, receiver fingers are quickly released from weak signal components and reassigned to stronger signal components, while maximum path diversity is maintained.

Abstract: An automatic routing is executed in the conventional manner for circuit components located at predetermined positions. Any unconnected place of the circuit is searched and the arrangement of the components relative to the unconnected place is modified. The automatic routing is performed again for the components the arrangement of which has been modified. Thus, the unconnected place can be eliminated from the circuit for a short time.
