摘要：

软件无线电所具有的灵活性、开放性等特点，使其在军民无线通信领域获得了广泛应用。以微电子技术和计算机技术为基础，利用计算机、MATLAB、FPGA和ADI公司的AD9364射频捷变收发器，设计了一种适合测试WCDMA、TD_SCDMA、GSM、LTE等通信系统的信号测试平台，该测试平台能生成任意数字化正弦波，实时检测通信信号的相关信息以及调整射频链路参数。实验结果表明，该设计符合软件无线电的设计思想，具有较强的通用性、可移植性和软硬件均可重构能力。

关键词: 软件无线电, FPGA, MATLAB, 射频捷变收发器

Abstract:

Software defined radio technology is widely used in military and civilian radio communication because of its flexibility and openness. Using computer, MATLAB, FPGA and ADIs AD9364 radio frequency (RF) agile transceiver, we design a signal testing platform for different mobile communication systems with varied characteristics, including WCDMA, TD_SCDMA, GSM and LTE. The testing platform can generate arbitrary digital sine waves, analyze the information of communication signals in real time and adjust the parameters of RF chains. Experimental results show that the communication signal testing platform is in accordance with the principle of software defined radio, and it has good versatility, portability and reconfigurability.

Key words: software defined radio, FPGA, MATLAB, radio frequency agile transceiver
