调制滤波器组主要包括复调制滤波器组和余弦调制滤波器组。
The complex modulated filter banks and cosine modulated filter banks are two main types of modulated filter banks.
若采用复调制法或直接抽取法等通用ZFFT法实现，一般要用专用设备或另作设计。
If the realization of the ZFFT was based on the method of complex modulated signal or directly decomposed signal, a special equipment would be used or designed in other way.
为了提高载波机的有效传输带宽，可采用多路数字韦瓦复调制的原理来实现载波机的单边带调制。
To increase the effectively transmitted bandwidth, digital multiplex channel Weaver complex modulation is employed to implement SSB modulation.
