Hardware Design Of Software Define Radio Intermediate Frequency Processing Module Based On Zynq

With the development of modern electronic technology and communication technology,existing test instruments and testing methods have gradually reached the technical bottleneck.The demand for human communication is growing rapidly,and the cost of hardware system input is getting higher and higher,making it difficult for traditional wireless communication systems relying on hardware to meet increasingly complex communication functions and increasing transmission index requirements.Software Define Radio(SDR)is a new technology that can be used to implement multiple communication systems in the field of wireless communication and to establish uniform standards for different systems.The software define radio platform utilizes scalable and reconfigurable application software to implement various functions in the wireless communication device on the standardized hardware device,and overcomes the shortcomings of the traditional wireless communication device,such as single function and poor scalability,and has strong flexibility and Open.As the main development direction of future communication technology,software define radio technology is bound to receive more attention and attention.The thesis considers Xilinx's Zynq-7000 series System-on-a-chip(SoC)processor and ADI's AD9361 single chip considering factors such as power consumption,cost,compatibility,and scalability.The zero-IF transceiver solution builds a hardware platform for software define radio IF processing modules,and carries out research and design of a highly integrated transceiver system based on Zynq.The main research contents of the thesis include:1.Compare several mainstream software define radio structure forms on the market,introduce the system structure of the software define radio IF processing module,analyze the composition of each function module,determine the overall implementation scheme of the system,and select the key components of the module.2.Study the solution based on the AD9361 single-chip zero-IF transceiver architecture communication link,design the corresponding hardware circuit;design the gain control system based on AD9361,and complete the system power module design according to the hardware overall scheme.3.Complete the hardware logic design of the signal interface and baseband signal processing of the software define radio platform in the FPGA to realize the core functions of receiving,processing and transmitting the digital baseband signal.4.Study the internal composition of Zynq processor chip and its software and hardware collaborative design scheme;research the SoC-based system integration design method and its on-chip AXI4 bus protocol specification,and complete the corresponding hardware logic design based on this protocol,build a software define radio Platform master module.Through the research and design of the above content,a miniaturized and highly integrated software define radio platform was finally built,and the hardware circuit and functions were tested and verified to realize its core transceiver function,it laid a solid foundation for the subsequent development of handheld transceivers based on the platform.
