导航接收机功率控制参数优化与性能分析

摘要

随着卫星导航接收机设计的越发复杂和先进，接收机功耗越来越高，对以电池供电为主的接收机来说是一个限制问题。功率控制技术是导航接收机实现低功耗行之有效的方法。对基本功率控制技术中的关键参数时间参数进行了优化分析，利用对锁相环进行暂态响应分析的方法，得出了最优的时间参数选取，同时进一步分析了功率控制对接收机性能的影响情况，为接收机在低功耗和性能之间的选择提供了参考。本文的结论可以直接指导接收机的功率控制设计。%With the design of satellite navigation receiver becomes more complex and ad-vance ,the receiver consumes much more power ,for the receivers which powered by battery it is an important limited question ,the power control technology is an efficient way to realize the lower power consumption of the receiver .This paper analyzes the key parameters of time for the basic power control technology .Utilize the analysis of PLL (PLL ,Phase lock Loop) transient response ,the basic requirement of time parameters selection is obtained ,and ana-lyzes the effect of power control on the receiver performance ,providing a reference to select betw een the receiver performance and low pow er consumption .T he conclusion of this paper could be used to guide the power control design of the receiver .
