碩士 === 明新科技大學 === 電機工程研究所 === 97 === The Discrete sine transforms (DST) can be applied to different fields according to the characteristic, in signal processing, digital filtering, image coding. This paper adopt row-column method for 2-D discrete sine transform implementation. The purpose of this method can reduce the implement cost. In this structure, We use a recursive algorithm to implement one-dimensional discrete sine transform (1-D DST), this algorithm decomposition to separate higher order DST into two low order DST, In order to reduce the circuit complexity, the algorithm propose a computing structure of recursive structure, which requires fewer multipliers and adders.
