An integrated circuit for facilitating spread spectrum reception of data having a data bit period includes an hypothesis search circuit () operable to correlate a pseudorandom code with a signal input based on a received signal to produce correlation results, and a processor circuit () operable to coherently integrate the correlation results over plural sample windows (PreD1, PreD2) staggered relative to each other in the coherent integration interval and to non-coherently combine the coherently integrated results corresponding to the plural sample windows (PreD1, PreD2) to produce a received signal output, whereby enhancing performance. Other circuits, receivers and processes are also disclosed.
