A method and apparatus of determining signal strength, regardless of the signal data rate, in a receiver receiving signals from a variable rate transmitter. The incoming signal is comprised of a series of frames. Each frame is comprised of a number of power control groups containing data. The number of the power control groups containing data within each frame is dependent on the unknown data rate. The position of the power control groups within the frame is a pseudorandom. The signal strength of an incoming signal of unknown data rate is determined based upon an active set of power control groups within a frame. The active set of power control groups contain data independent of the unknown data rate. This signal strength information may be used to indicate that the signal strength is sufficient to perform further signal processing.

A method of determining a signal strength of an incoming signal in a system receiving variable rate data wherein said incoming signal is comprised of a series of frames, each frame having a corresponding unknown data rate, each frame comprised of a plurality of data segments wherein the number of said data segments containing data in each frame depends upon said corresponding unknown data rate, said corresponding unknown data rate may correspond to one of at least a highest data rate and a lowest data rate, said method comprising the steps of: receiving a first energy value corresponding to a first one of said data segments; and summing said first energy value with a previously accumulated total if said first one of said data segments corresponds to a data segment containing data at said lowest data rate to produce an estimate of said signal strength.
