【摘要】 为了解决软件无线电信号处理过程中同一系统不同方案引起的差异问题,采用互相关评估准则,以相关算子为理论依据,相关系数为评估指标,分别利用Hamm ing窗、Db3-3小波、时域加Kasier窗和Db3-4小波基四种不同方法,分析了标准测试信号的选取理由和依据。Matlab仿真结果表明:互相关评估准则可应用于不同处理信号差异的效果评估,是一种归一化、定量的时域评估方法。更多还原

【Abstract】 In order to solve difference due to different plans of the identical system in the software radio signal treating processes,the paper discusses the uses the mutual correlation appraisal criterion and correlation-index for appraisal target and the separately uses of the Hamming window,Db3-3 wavelet,adds the time domain to the Kasier window and Db3-4 wavelet base four different methods.The standard spike selection reason and the basis are.The Matlab simulation result indicates: The mutual correlation appraisal criterion may apply to the different signal processing and difference effect appraises and is one kind of normalized,the quota time domain appraisal method.更多还原
