Abstract

This invention provides a signal synchronizer that is capable of minimizing the effects of multi-path reception. The signal synchronizer provides signal samples from a first signal source and a second signal source for generating an output signal. The signal synchronizer includes a memory for storing signal samples obtained from a first signal source and for storing signal samples obtained from a second signal source. Circuitry in the synchronizer determines a signal transit time difference between the first signal source and the second signal source. A readout controller then determines a memory offset from the signal transit time difference. The memory offset specifies a location in the memory from which to begin reading the signal samples obtained from the second signal source.
