无线定位系统中自动增益控制电路的设计与研究
Design and research on automatic gain control circuit in wireless positioning system
摘要
Abstract
Since the civilian requirement of satellite wireless positioning system is increased,the cheaper and lower⁃power consumption RF receiving front⁃end technology is studied and explored for business. A digital programmable gain control system used for wireless positioning system was designed and implemented,which can be applied to the emerging IMT⁃Advanced new generation 4G wireless communication network. The analog control mode and digital programmable mode are analyzed systemati⁃cally. The mathematical model of the system was established to study the feasibility. The different realization forms of the speci⁃fic module are described while designing the chip,and the optimizable structures are proposed.关键词
