ABSTRACT:
A high speed multiplexed digital correlator device for correlating serial data against reference data. The device includes a plurality of digital correlators configured to operate in parallel with their operations overlapping in time. The serial data is divided between the plurality of correlators by multiplexing means. The outputs of the plurality of correlators are summed to produce an overall correlation output signal. Due to the multiplexed configuration, the individual correlators operate at a much lower rate than the data rate of the serial data to be correlated. Also disclosed are synchronized mutliplexed correlators including multiple multiplexed correlators for correlating serial data differing in phase relationship with the reference data against which it is to be correlated.
