摘要

我们提出了计算离散余弦变换(DCT-IV)和离散正弦变换(DST-IV)的递归实现。我们还提出了一个递归结构，可用于同时计算DCT-IV和DST-IV。我们使用克伦肖递归公式(CRF)得到DCT-IV和DST-IV的递归结构。所有这些结构都很容易适用于使用模块化结构的VLSI实现。

Recursive implementation of the DCT-IV and DST-IV

We present recursive implementation for the computation of the discrete cosine transform (DCT-IV) and discrete sine transform (DST-IV). We also present a recursive structure that can be used to simultaneously compute the DCT-IV and DST-IV. We use the Clenshaw's recurrence formula (CRF) to obtain recursive structures for the DCT-IV and DST-IV. All these structures are easily amenable to VLSI implementation using modular structures.
