array processing computation的意思|示意

In this paper, we preset the processing elements based on a special butterfly computation and discrible the systolic array implementations for computing DCT, DHT(DWT) and DFT respectively.

文中绐出了两种基于特殊蝶形运算的处理单元和两种计算DCT，DHT（DWT）和DFT的脉动阵列实现。

In array signal processing, the fourth-order cumulant can be applied to extend array virtually and enlarge aperture of array antenna, but computation load of algorithm would also increase.

在阵列信号处理中，利用四阶累积量可以使阵列虚拟扩展，增大了天线阵的孔径，但同时也增加了算法的计算量。
