Design of Solider Spread Spectrum Networked Radio Based on ARM

设计了基于ARM技术的具有较高传输速率和扩频增益的全数字化单兵网络电台。核心处理器充分考虑了多任务和实时性的要求,采用ARM处理器及嵌入式操作系统uC/OS-II,扩频基带处理器选用扩频处理增益和集成度较高的AMIS-50050芯片,话音采用高压缩比的AMBE压缩算法,语音质量高,组网遵循Ad hoc组网协议。该电台的设计满足单兵对数据、话音、图像传输和系统组网的要求,并具有高性能、高集成度、抗干扰、抗截获、体积小和功耗低的特点。

This paper proposes a design of the soldier digital networked radio with higher data rate and DSSS gain based on ARM. The core processor uses ARM processor and uC/OS-II, which is a multitask and real time embedded system. Spread spectrum baseband controller uses AMIS - 50050, which has high processing gain and integration. Voice compression is based on AMBE. It uses ad hoc networking protocol. This design can satisfy the requirements for data, voice and image transmission and system networking, and has such characteristics as high performance, high integration, anti-jamming, anti-interception, lower power and small size.
