Lire la suite >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.Lire moins >
