Then, ICA-R was used in subband to extract the estimated target signal we were interested in. Finally, after synthesis filter banks, shrinkage function was used to enhance estimated target signal further.
首先对两路带噪语音信号进行子带分解;然后在子带内利用ICA-R算法从带噪语音信号中提取出子带目标信号,再经过子带综合滤波器形成全带目标信号;最后,将该信号经收缩函数后处理,得到增强后的目标语音信号。

再对半带滤波器进行谱分解，构造出了各分析和综合滤波器。
By implementing spectrum factorization on the half-band filters, all the analytic and synthetic filters were constructed.
滤波器的元件值不是用一般的综合方法，即从输入阻抗中逐个移去全极点或部分极点，而是用极点交换法求得。
The element values of filters can be calculated by permutation method instead of the usual synthesis, i. e. successive complete and partial pole removals from the input impedances.
