The effects of raised‐cosine filtering on the processing gain of acousto‐optic correlators (AOC) in direct‐sequence spread‐spectrum receivers are considered. For ideal AOCs, analytical expressions are derived for the full roll‐off filter characteristics. The results are given in terms of the ratio β of the code rate to the filter bandwidth. For real AOCs, results are obtained from numerical simulation and are compared to previous results obtained for other types of filters. © 2008 Wiley Periodicals, Inc.
