中文摘要 | 鏡射濾波器由於能構造一有效率之多取樣率(Multirate) 訊號處理系統,使得訊號可以分解成不同次頻帶,根據各次頻帶訊號特性利用不同演算法處理,處理完後再加以合成,在多取樣率訊號處理系統中扮演著重要角色,隨著網際網路多媒體影像及視訊需求等應用日趨廣泛,如何有效設計滿足完美重建鏡射濾波器的硬體實現,將隨著產品數位化及多媒體等應用需求之增加而愈形重要。 近年來由於超大型積體電路製作技術的進步,相對也帶動了數位訊號處理器快速發展,數位訊號處理器晶片的功能強且執行效能高,故適合使用於即時訊號處理的應用,本論文利用德州儀器公司所製造的TMS320C6711 高效能數位訊號處理晶片,來實現適用多取樣率之完美重建鏡射器設計,此論文成果對未來數位化多媒體即時影像與視訊的壓縮與傳送系統將扮演重要角色。 |
英文摘要 | Quadrature mirror filter (QMF) banks have received much attention since they can be successfully used to constitute a multirate signal processing system for splitting a signal into subbands and allowing the re-synthesis of the signal from the subbands. For the increasingly real-time applications on multimedia, it is important to find more efficient algorithm that can meet the real-time requirement. Recently, the digital signal processing chips have been well-developed due to the progresses in the VLSI technology. The DSP chip is very powerful in its processing and object-oriented architecture. Therefore, the DSP chips are very suitable for the applications of real-time signal processing. In this project, we will apply the TI TMS320C6711 high performance DSK to implement the perfect reconstruction QMF banks with least-squares response. The results will play an important role for the digital products and multi-media communication applications. |
