由于多小波变换系数的计算是直接与其预滤波方式相联系的，而在单小波变换系数计算中之所以能由近似表示就是因为尺度函数具有低通特性和平移正交性，由此我们研究了能满足以上要求的预滤波，并对离散小波变换系数和连续小波变换系数之间的差异作了分析，从误差分析结果我们可以预见：为了减少误差我们可以通过对预滤波的进一步设计来控制。 | | 7. | The adaptive front - end has the adaptive ability for the magnitude and frequency of input signals . it can prefilter for the input signals , eliminate the useless signals , and improve the dynamic range of receiver system . it can lessen the burden of digital signal processing in the back - end of receiver , and improve the performance of receiver system
自适应接收机前端对输入信号有自适应能力? ?频率自适应和幅度自适应,这样的前端就可将系统的接收中心频率和带宽自适应到输入信号的频率和带宽,其实就是对输入信号进行一次预分选、预滤波,剔除对接收系统毫无作用的信号;同时对大信号自动减小增益,对小信号增加增益,提高系统的动态范围;而且可以对干扰信号进行压制。 | | 8. | Finally , the author argues that prefiltering a discrete signal is a necessary step before using unbalanced multiwavelets . in this thesis , the author applies orthonormal perfiltered and first - order balanced multiwavelet to the compression of ecg data respectively . by using orthonormal perfiltered we can acquire a better result than by using first - order balanced multiwavelet or by using single wavelet
对多小波而言，在变换之前对离散信号进行预处理是必须的，我们分别采用正交预滤波和一阶平衡后的提升多小波对心电信号进行压缩，正交预滤波的效果好于一阶平衡，也好于一般的单小波。 |
