Multiple-dwell and sequential code acquisition with diversity for FFH/MFSK spread-spectrum systems under band multitone jamming

Abstract

Pseudonoise code acquisition is investigated for constant hopping rate fast frequency-hopped (FFH)/M -ary frequency-shift keying systems under the effects of white Gaussian noise and band multitone jamming. In particular, serial search acquisition systems based on the traditional multiple-dwell test (up to three dwells) and three novel sequential tests are analyzed and compared. Analytical results show the following in a heavily jammed environment: 1) the inherent time diversity in an FFH system can significantly improve the acquisition performance of the multiple-dwell test and 2) the novel sequential tests can significantly outperform the multiple-dwell test. Our analytical results are verified by computer simulations.
