在Z-变换域中,解反褶积方程即可直接求出脉冲响应。主要假设条件是奇一深度模型,也就是说,至边界的双程旅行时只限于奇整数。另一个假设条件是,已知子波序列的长度小于数据序列长度的一半。脉冲响应的倒数受源函数的零位采样所约束。所得的不定方程组可由奇-模型所提供的方程进行补偿。根据多项式除法获得的倒数,即可求得脉冲响应。 In the Z-transform domain, the deconvolution equation can be directly obtained impulse response. The main assumption is the Odd-and-Depth model, that is, the two-way trip to the boundary is limited to odd integers. Another assumption is that the length of the known wavelet sequence is less than half the length of the data sequence. The reciprocal of the impulse response is constrained by zero-bit sampling of the source function. The resulting system of indeterminate equations can be compensated by the equations provided by the odd-model. According to the inverse of the polynomial division, you can find the impulse response.
