Abstract: An apparatus for post-correlation signal processing includes a plurality of correlators for correlating a received signal with a predetermined signal to produce a plurality of correlator output signals and a selection circuit coupled to the plurality of correlators for selecting a correlator output signal from one of the plurality of correlator output signals to provide a selected correlator output signal. A memory is coupled to the selection circuit for storing post correlation totals. A counter is coupled to the memory for synchronizing the memory with the predetermined signal. An adder is coupled to the memory and to the selection circuit for combining the selected correlator output signal with the post correlation total from the memory to form a new post correlation total. The memory replaces the previous post correlation total with the new post correlation total.
