An improved method and apparatus for measuring the strength of a radio frequency (RF) signal (Fig. 3) subject to Rayleigh fading is described. The strength of the RF signal is sampled two or more times during a predetermined time interval and the sampled signal strength having the largest magnitude is selected (Fig. 4). The selected signal strength is a reasonably accurate measure of the signal strength since the true average strength of a Rayleigh fading signal is close to its peak signal strength. The inventive method and apparatus is particularly well adapted for use in a scanning receiver (Fig. 2) located in a base station radio (111, 121 131) of a cellular, radiotelephone …
