• Resumen

  • The effects of signal filtering on the processing gain in acousto-optic correlators (AOC) in direct-sequence spread-spectrum receivers are considered. Different filters are considered. The results are given in terms of the code rate to the filter bandwidth. Analytical expressions are derived for ideal AOC’s. For real AOC’s results are obtained from numerical simulation.
