Re: [oc] RS Codec

yeah , that's fine. i have intelsat specs for IDR modems , we can just
take mod , demod portion of the specs and try an all digital
implementation , did u think abt testing , simulation and other stuffs ?
how shall we do it ? intelsat specs , i don't have a soft copy and so i'll
write abt mod demod portion alone at the time of starting...
bye
