Viterbi decoding

Started by israilsaifi May 9, 2007
Hi all
I want to implement viterbi decoding for frequency selective fading
channel in matlab could u tell me how i should start writing program ? 
thanks

Please, John, he said Matlab, not C or C++. [decoded_bits] = function viterbidecode(y, code) % % Viterbi decoder code. %

Oh, sorry I jumped the gun. Matlab has a decoder builtin to the comms toolbox. Without additional info from the OP it's hard to say how it might help equalize the channel. >> help vitdec VITDEC Convolutionally decode binary data using the Viterbi algorithm. DECODED = VITDEC(CODE,TRELLIS,TBLEN,OPMODE,DECTYPE) John
