提出了一种结合空间/时间子带分解的自适应宽带波束形成结构。接收到的信号首先通过变换矩阵进行处理，然后被分成一系列子带，在这些子带中可以操作独立的波束形成器。一个特殊的属性是，一些较低的子带可以被丢弃，而不影响其性能，这导致了一个系统具有较低的计算复杂度和较高的收敛速度。
An adaptive wideband beamforming structure is proposed with combined spatial/temporal subband decomposition. The received signals are first processed by a transformation matrix, and then split into a series of subbands, where independent beamformers can be operated. A special property is that some of the lower subbands can be discarded without affecting its performance, which leads to a system with a lower computational complexity and higher convergence speed.
