I need to insert a Viterbi decoder routine ( 1/2, k=7 ) in a program. Speed isn't a concern, as I will receive only 50 bits/minute. Is there some assembler code available anywhere ? I have found nothing searching with Google. Thanks.--- Marcelo Puhl mark@cpovo.net http://py3ss.cjb.net -- http://www.piclist.com hint: The PICList is archived three different ways.
