[VHDL-FPGA-Verilog] digital-quadrature-down-converter DL : 0: 基于FPGA的数字正交下变频器设计,在ALTERA的DE2开发板上设计一个多相滤波结构数字正交变换器。其中多相滤波模块是最关键模块，该模块将64阶滤波器的系数分成奇偶两路，并通过VHDL常数的方式存储在模块内部。这些常数是通过在MATLAB中调用FDATool，根据滤波器的参数要求来生成的。这些浮点格式的滤波器系数还需要在MATLAB中计算成二进制补码的形式，才可以存储在模块中。-FPGA-based digital quadrature down-converter design, ALTERA the DE2 development board to design a polyphase filter structure of the digital quadrature converter. Polyphase filter module which is the most critical module, 64-order filter coefficients are divided into two parity, and stored by VHDL constants inside the module. These constants are called by MATLAB FDATool, according to filter parameters required to generate the. These floating-point format in MATLAB filter coefficients need to be calculated into a binary form of complement, it can be stored in the module.
