Digital radio communication
A method of operating a digital radio receiver comprising: receiving a radio signal; passing said radio signal to a correlator for correlating said radio signal with a predetermined pattern to provide an output signal comprising a plurality of peaks separated in time; determining an amplitude of a first peak in the plurality of peaks; calculating a selection threshold based on said first peak amplitude; determining an amplitude of a second peak in the plurality of peaks; comparing said second peak amplitude to the selection threshold; and identifying the second peak as a correlation peak if the second peak amplitude is greater than the selection threshold.
