Abstract:
A method for operating a radio subscriber unit having a diversity receiver apparatus including at least a first antenna and a second antenna, wherein the first antenna is at least partially uncorrelated with respect to the second antenna, the method comprising the steps of:receiving a first representation and a second representation of a composite radio frequency (RF) signal from the first antenna and the second antenna, respectively, wherein the composite signal includes a desired direct sequence-code division multiple access (DS-CDMA) RF signal and interfering signals, and wherein the desired DS-CDMA RF signal includes at least one coded pilot signal;determining at least one ratio of the at least one coded pilot signal to an estimate of the composite RF signal responsive to receiving at least one of the first representation of the composite RF signal and the second representation of the composite RF signal; andcontrolling a selected state of the first antenna and the second antenna responsive to the at least one ratio.
