Abstract
A finger assignment system prevents the assignment of receiver fingers to the same multipath component and to avoid the inefficiencies associated with current schemes. The finger assignment system accomplishes this by setting an offset or delay difference between the offsets or delays assigned to any two fingers, and if the offset or delay difference is violated, adjusting the offset(s) or delay(s) of one or both of the fingers to differ from each other by at least the offset difference. In certain embodiments, the receiver establishes an offset or delay difference between the offsets or delays assigned to any two fingers which are receiving signals from the same antenna. If the offset difference is violated, the finger assignment system adjusts the assigned offset or delay of the weaker finger to differ from the assigned offset of the stronger finger by at least the offset difference. Thus, the receiver scheme according to the principles of the present invention tends to have more receiver fingers tracking more multipath components a higher percentage of the time. The more effective use of the receiver fingers according to the principles of the present invention tends to increase the multipath diversity of the receiver and to improve the average SNR of the receiver.
