    Abstract: 此篇論文主要在陳述一種新的維特比解碼器(Viterbi decoder)的架構,目的在 提高原有IS-95, IS-2000, 8021.x的傳輸率。就原IS-95標準,其輸入頻率為10 MHz,而其傳輸率為1.22 Mbps,如果使用此架構,可將其傳輸率提升至40 Mbps,其改善倍率將近32倍。如果以IS-2000為比較(3.1 Mbps),此架構的改善 倍率,亦可達到12倍之多。而如果以現存的802.11 a/b/g,可將其原有的輸入觸 發頻率40 MHz降至10 MHz,其輸傳輸率仍可維持在27 Mbps,甚至達到40 Mbps。 並且在未來的802.11n標準下,其傳輸率必須達到100 Mbps,如輸入頻率維持在 40 MHz,此架構可提供到160 Mbps的傳輸率,仍然遠超過802.11n的標準。而且 也可大幅減少生還者路徑(Trace back unit)單元所佔積體電路的面積。
