Abstract
Two-level schemes use two decision stages to ascertain coarse code acquisition of spread spectrum signals. The first stage employs passive correlators which are capable of real time search but with lim-ited reliability. The second stage employs active correlators which allow longer integration times and more reliable decisions but which cannot search in feal time. By using these stages in tandem the advantages of real time rapid search and reliable decisions can be obtained. We have developed several such schemes along with analytical models to characterize their performance in severe environments that include fading and noise jamming.
