摘要：in tactical communication where the quality of signal is option for the secure transmission,ContinuouslyVariable Slope Delta modulation(CVSD) codec is used which is very difficult to decodeif intercepted because of itsadaptive nature and likewise its parameters.In communication systemswhere this codec is widely used, required a methodto detect or identify the bitstream of this kind.in this paper we attempt to extend classifier algorithm[6] to identify CVSDcodec by extracting 7 different parameters for each windowsize operation from the incoming unknown bit stream andcompare with the thresholds are already calculated and stored in database.operations are performed on different slides8,10,16,24 and 32 to extract total of 35 parameters,all these parameter values are added to previous already existinglibrary[6].
