手持北斗双模型接收机总体设计与关键技术

Overall Design and Key Technology of Hand -held BeiDou Dual- mode Receiver

本文以手持北斗双模型接收机研制为背景，提出了系统总体方案，对天线、射频、抗干扰AD等硬件模块，信息处理和星控软件，以及系统结构进行了设计，对接收灵敏度、捕获策略、低功耗设计等关键技术进行了研究；最后，从接收灵敏度，首次定位时间、通信成功率等方面进行了实验，验证了方案的可行性。

Based on the development of hand - hald Beidou dual - mode receiver, an overall system scheme is proposed, hardware modules （ including antenna, radio frequency, anti - resistance AD etc. ）, information processing and display ＆ control software, and system structure are designed. Key technologies such as receive sensitivity, acquisition strategy, and low power design are studied. Finally, feasibility of the scheme is validated through experiments on the sensitivity, Time to First Fix, communication success rate, and so on.
