摘要
The discrete W transform (DWT) is widely used in digital signal processing. This paper proposes a novel approach to compute DWT via computation of the first-order moments without multiplications. A scalable and efficient systolic array is designed to implement this approach. Compared with the other existing methods, the proposed algorithms are simpler and more applicable.
