- W2006553653 abstract "ABSTRACTTwo -level schemes use two decision stages toascertain coarse code acquisition of spread spectrumsignals. The first stage employs passive correlatorswhich are capable of real time search but with lim-ited reliability. The second stage employs active correlators which allow longer integration times andmore reliable decisions but which cannot search inreal time. By using these stages in tandem theadvantages of real time rapid search and reliable decisions can be obtained. We have developed several such schemes along with analytical modelsto characterize their performance in severe environ- ments that include fading and noise jamming.1. INTRODUCTIONTwo common forms of spread spectrum signal-ing employ either direct sequence or frequency hop- ping modulation. Either can be demodulated usingmatched filter structures without requiring code acquisition. Examples are RADA (random accessdiscrete address) and PAMA (pulse address multipleaccess) schemes which employ short codes assignedto receivers. However, in low SNR applications, orfor security in LPI (low probability of" @default.
