摘要
采用Gardner算法,对QPSK调制解调系统中的位同步系统进行设计与实现,大大提高了系统性能和资源利用率。重点阐述采用FPGA开发环境System Generator系统设计工具进行位同步设计与实现的方法,并在Lyrtech SFFSDR DP(Lyrtech小型软件无线电开发平台)上进行硬件协同仿真与验证,同时给出了相应的仿真波形。仿真结果在软件无线电技术及应用方面有着重要的理论研究价值,在开发设计上可大幅度地缩短开发周期,节约成本。
The Gardner algorithm is adopted to the design and realization of symbol synchronization in the QPSK modulation and demodulation system,which can greatly improve system performance and resource utilization .The method of how to use the xilinx system generator system design tool to design and realize symbol synchronization is especially expounded,at the same time,the new idea of FPGA hardware-in-the-loop co-simulation and attestation on the Lyrtecb SFF SDR DP is provided. Also the relevant simulation wave is shown. Simulation is conducted,which provides an important theoretical research value in software defined radio technology and applications. The method is used to shorten the development cycle and save cost.
