该文对比分析了无线通信系统中采用三种不同架构技术实现的宽频段接收机的优缺点,针对下一代无线通信平台中对接收机的宽频带、可配置、小型化、低成本、低功耗需求,设计了一种采用基带、射频一体化架构基于AD9361的宽频段接收机,并对其AGC算法进行了详细介绍;最后对接收机的接收灵敏度和AGC响应时间进行了测试验证,结果表明该方案设计的接收机在接收机灵敏度及AGC响应时间等性能方面可以满足下一代无线通信系统平台需求。

This paper compares and analyzes the advantages and disadvantages of the wideband receiver ofthree different architecture technologies in the wireless communication system.In view of the wideband,configurable,miniaturized,low cost and low power consumption requirements of the receiver in the next generationwireless communication platform,a wideband receiver based on AD9361 using the baseband and radio frequencyintegration architecture,is desigend and Its AGC algorithm is introduced in detail.Finally,the receiversensitivity and AGC response time of the wideband receiver are teseted and verified.The results show that thewideband receiver designed by this scheme can meet the requirements of the next generation wireless communicationsystem platform in the receiver sensitivity and AGC response time.
