Abstract
Apparatus having corresponding methods and computer-readable media comprise a receiver adapted to receive a plurality of single-frequency network (SFN) signals at a predetermined frequency; a correlator adapted to correlate the SFN signals with a predetermined reference signal, wherein correlating produces a plurality of correlation peaks; a grouper circuit adapted to group the correlation peaks into arrival groups such that the correlation peaks in different arrival groups are known to be from different transmitters; and a selection circuit adapted to select the earliest correlation peak in each arrival group as a leading correlation peak.
