Interference power estimation for adaptive antenna system
First Claim
Patent Images
1. An apparatus, comprising:
- a rake receiver of a communication system having an adaptive antenna transmitter, the receiver comprisingfirst input means for receiving a beam signal,second input means for receiving an antenna signal, andestimating means, operatively connected to the second input means, for estimating the interference power of the received beam signal for each rake finger of the rake receiver and for averaging the interference power for said rake fingers, wherein said estimating means utilises channel estimates of said antenna signal to estimate said interference power.
