The Design And Research Of IEEE802.11a Baseband Transmission System Based On Zynq Platform

At present,the software radio has a broad space for development in civil research.In the field of wireless communications,there are many communication protocols.Because of new protocols couldn't be compatible with old protocols,leading to difficulty upgrading.As the software radio platform using software for technological innovation,the platform has a certain degree of flexibility and high adaptability,to achieve compatibility with the old communication protocol,at the same time through the software to update the latest agreement.The large number of studies have shown that,in order to adapt more rapid development of the communication environment,only use of FPGA to achieve software radio transmission system,there will be many deficiencies,they need to improve the processing speed,communication stability,human interaction and other additional functions.The design uses the Zynq-7000 series which research by Xilinx's latest development,its the latest technology who integrated the ARM processor and FPGA programmable logic devices in a chip.To achieve the newest generation of programmable system-on-chip.Using the single-chip solution to achieve the software radio platform,can be have perfect compromise in the performance,cost,power and other design budget.This disstation design the software radio platform for Zynq-7000 series combined with AD9361 agile radio frequency transceiver developed by ADI company.First of all,this disstation analysis how to realize the hardware and software structure,mainly analyzes the underlying hardware interface,platform processing system,system startup and so on.Finally,using the Matlab software GUI tool to implementation the IEEE802.11a baseband transmission to verify the realization of the software radio platform.Finally,analyzed the results of IEEE802.11a baseband transmission are systematically.
