改进的GNSS信号快速捕获检测算法
Improved algorithm for rapid detection in GNSS signal acquisition
摘要
Abstract
To ensure fast acquisition of satellite signals in high dynamic applications , an improved algorithm was proposed for signal detection during acquisition by global navigation satellite system .The algorithm combined the advantages of the M-of-N and Tong detection algorithms .Through the multi-threshold detection mechanism , the de-tection and rejection speed accelerated whether the signals exist or not .Numerous real data tests show that the im-proved algorithm is three times faster than the M-of-N detection algorithm and one-third times faster than the Tong detection algorithm without any performance deterioration .关键词
