Hybrid parallel PN code acquisition technique for LEO satellite communication
通讯扩频序列混合并行捕获预检测积分时间和判决门限最优设计

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