Description: 为了解决软件无线电通信系统中频采样之后的极大数据量在基带处理部分对DSP计算的压力,常采用多速率处理技术.多速率处理过程中需要使用积分梳状滤波器、半带滤波器和高阶FIR滤波器.在分析了积分梳状滤波器的结构和特性的基础上,阐述了多级CIC滤波器一种高效的FPGA实现方法,该方法的正确性和可行性通过Quartus Ⅱ的时序仿真分析得以验证,实际中可以推广应用.-In order to solve software-defined radio communications system after IF sampling of great amount of data to the DSP in the baseband processor part of the calculation of the pressure, often using multi-rate processing technology. Multi-rate processing need to use the integrator comb filter, half-band filters and high-order FIR filter. in the analysis of the integrator comb filter structure and characteristics, based on the multi-stage CIC filter described an efficient FPGA implementations, the correctness and feasibility of the method adopted by the timing Quartus Ⅱ simulation analysis can be verified in practice can be applied.

Description: 文中应用软件无线电思想对数字下变频器中的几个关键技术进行了研究,对下变频各个模块所涉及到的CIC、HB、FIR等关键算法进行了讨论、提炼与总结,应用matlab软件设计了下变频器中的CIC、HB、FIR滤波器等核心模块,并将各模块融为一体从软件实现的角度完成了对系统的搭建和功能仿真.仿真结果表明,系统实现了对中频信号的下变频处理且无失真现象,大大减少了软件无线电系统数宁信号处理的运算量和数据的存储量,极大地提高了系统的实时性.-The paper application software radio digital down converter in the thinking of several key technologies have been studied for the next conversion involved in each module to the CIC, HB, FIR and other key algorithms were discussed, refined and summarized the application of matlab software design downconverter in the CIC, HB, FIR filters and other core modules, and integration of various modules from the software point of complete structures and functions of the system simulation. The simulation results show that the system achieved the right under the IF signal Frequency processing and without distortion, thus greatly reducing the number of software-defined radio system, rather the amount of signal processing operations and data storage capacity, greatly improve the system in real time.
