Abstract
In one aspect this invention provides a method to operate a receiver, and includes applying signals received from at least first and second antennas to corresponding first and second finger pairs, where each finger pair comprises a first finger member and a second finger member, and outputting traffic symbols and pilot symbols from each finger member; space combining weighted pilot symbols for each pair to produce a noise plus interference estimation for the pair under consideration; combining the noise plus interference estimation of each pair to generate a cumulative noise plus interference estimate; subtracting the cumulative noise plus interference estimate from an estimate of the total signal energy input to a channel decoder to generate an unbiased total signal estimate; and dividing the unbiased total signal estimate by the cumulative noise plus interference estimate to obtain an unbiased and accurate signal to interference plus noise ratio estimate that accounts for both space correlated and uncorrelated interference terms.
