实际上，复交替投影神经网络不仅可用于信号处理中的带限信号外推，还可用于选频、陷波等场合。

In practice complex alternating projection neural networks can be widely applied to signal processing, such as band-limited signal extrapolation, frequency selector and trap filter.

在交替迭代过程中，考虑到算法收敛较慢，一种称为向量外推的加速方法被采用。

During the alternate iteration, an acceleration method called as vector extrapolation was applied to the alternate iteration steps owing to slow convergence of the algorithm.
