Abstract

A hybrid Parallel PN code acquisition scheme is investigated for burst mode spread spectrum communication with high doppler frequency offset. Based on LEO satellite channel, analysis of post detection integration and detection threshold to average acquisition time are given. Aimed at minimum acquisition time, an optimal threshold and post detection integration are put forward in this paper.

Key words： spread spectrum system; parallel acquisition; post detection integration; adaptive threshold
