Software implementation and algorithm analysis of DDC

Yu Li

Abstract

Wide band high bit rate digital signal can be transformed to narrow band low bit rate digital signal with DDC technology,so can be processed by DSP in real time After analysing the model of DDC technology,a software implementation methods of DDC,which have more efficiency,more flexibility and adaptability than normal DDC ASIC,are presented
