Practical circuit design and implementation of the communication with the absolute encoder)

数字下变频（DDC）在如今基于软件无线电的架构中对系统的整体性能决定性的影响，代码为基于Matlab的4通道DDC程序，程序中可以根据需要调节滤波器等参数评估DDC的性能对于使用FPGA实现DDC有较大的参考价值(Digital down conversion (DDC) in today' s architecture based on software radio system a decisive impact on the overall performance of the code for the 4-channel DDC Matlab-based program, the program can be adjusted according to filter parameters such as the use of performance assessment FPGA DDC DDC has achieved great reference value)

modelsim仿真，大量vhdl程序，验证，很有价值！(The ModelSim Simulation, a large number of VHDL procedures, validation, great value!)

该模块已经成功运用在xilinx xc6slx45t，xc6slx75t多个产品中，经过实践证明，采用dna及其加密算法加密是一种成本低廉（无需另外加密芯片）可靠的加密手段。Xilinx Spartan-6 FPGA读取DNA数据并进行比较，产生比较结果信号输出。附带有xilinx DNA.ppt说明及调试注意事项。(The module has been successfully used in xilinx xc6slx45t, multiple xc6slx75t products, proven, and the encryption algorithm uses dna is a low-cost (no additional encryption chip) reliable means of encryption. Xilinx Spartan-6 FPGA reads the data and compare DNA to produce a comparison result signal output. Xilinx DNA.ppt comes with instructions and commissioning notes.)
