摘　　要：描述了一种低功耗扩频全双工卫星收发机通用基带处理结构。此构架采用了一系列针对低功耗卫星通信的优化,包括频域抗干扰算法、插值技术、频域并行捕获算法和双级AGC技术,可以满足常用卫星通信地面设备的需求。Satellite communication is an important part of emergency communication. A low-power-consuming baseband architecture for satellite spread-spectrum trans-receiver is given. The architecture is optimized for general purpose compact satellite trans-receiver. Combined with anti-jamming, interpolation, frequency domain parallel signal detection and double AGC technology, this architecture can fulfill the demands of commonly used satellite ground system.
