A method of estimating the total Received Signal Strength Indicator (RSSI) for a receiver which is arranged to combine signals from a plurality of antenna elements, the method comprising: coherently summing the channel estimates h(i) for each finger of the receiver to provide a coherent sum; and calculating the magnitude of the coherent sum. An estimate of the Interference Signal Strength Indicator (ISSI) is made for each finger. The total ISSI is calculated as a function of individual ISSIs for each finger. An estimate of the Signal-toInterference Ratio (SIR) is calculated from the total RSSI and total ISSI, and not from summing individual SIRs for each finger. |
