摘要
立足软件重构技术,建立数字解调器模型,从模块层级出发,按照"组件-模块-算法-模型"的重构思想,分解解调流程,生成解调算法组件库;并依托组件库函数,适当进行功能重构和添加,重构生成8种常见调制信号的解调算法;最后通过仿真实验验证重构生成的数字解调器的正确性,并以QPSK信号解调算法为基准,对解调算法重构中组件复用率进行定量统计和分析。
Based on software refactoring techniques, this paper establishes the model of digital demodulator. On the module level, according to the refactoring idea of "component-module-algorithm-model", the demodulation process is decomposed, and a component library of the demodulation algorithm is generated. And based on the component library function, eight demodulation algorithms for common modulation signals are generated through functional refactoring and adjunction. Finally, simulation results verify the validity of the digital demodulator generated through refactoring, and using the QPSK signal demodulation algorithm as a benchmark, quantitative statistics and analysis are conducted on the reusability of the components in the refactoring demodulation algorithm.
