An approach for designing multiwavelets is introduced, for use in cardiac signal processing. The parameterization of the class of multiwavelets is in terms of associated FIR polyphase all-pass filters. Orthogonality and a balanced vanishing moment of order 1 are built into the parameterization. An optimization criterion is developed to associate the wavelets with different meaningful segments of a signal. This approach is demonstrated on the simultaneous detection of QRS-complexes and T-peaks in ECG signals.
介绍了一种用于心脏信号处理的多小波设计方法。多小波类别的参数化是根据相关的有限脉冲响应(FIR)多相全通滤波器进行的。参数化过程中内置了正交性和一阶平衡消失矩。开发了一种优化准则,以便将小波与信号的不同有意义段相关联。在心电图(ECG)信号中QRS复合波和T波峰的同时检测中展示了这种方法。
