摘要
Abstract
Acquisition is a very important part of digital GPS receiver. The acquisition of weak GPS signal is a key point of the research of GPS algorithm. Two classic acquisition strategies, TONG strategy and NM strategy, are analyzed and compared. Considering the specialty of weak signal condition, a new acquisition strategy named Double Threshold(DT) strategy is proposed. The analysis and simulation indicate that it performs well under weak signal condition.关键词
