hi cores, VHCG is updated! It is a viterbi hdl code generator. The homepage of VHCG is http://www.opencores.com/projects.cgi/web/vhcg/overview. You need to setup the code words of covolutional code, for example, (91,121,101,91) for Rate=1/4 K=7 code used for DAB. The RTL code is implemented in verilog. It use traceback method to decode convolutional code. If you meet some problems about it, please email to me.
