need Convolutional Decoding Algorithm

convolutional coding viterbi decoding

hello,

i am working on 1/2 rate convolutional encoding/decoding, the encoding part is very easy, but i am not getting the decoding part, can any body help in this regard

Thank you,
Narendra

Salam,

U need to know the viterbi decoding algorithm.
U can find it explained briefly in " Wireless Communication - Andrea goldsmith ", you can find it at the book upload section.

Hope that helps.

regards,

U can also refer to " Digital Communications" to get more informations about viterbi decoding algorithm.

Hope this helps,

If you want the decoding algorithm for Convolution Encoder First you refer the matlab command "vitdec" i.e Viterbi Decoder.

i think it may help you littlebit

For initial understanding of 1/2-rate Viterbi decoder, use "digital communications, fundamentals & Applications" by saklar... specially its Viterbi decoding example is very illustrative....

1st hand info about traceback length, puncturing and soft/hard decision of VD is ava in matlab helpdesk for "vitdec" command..

me too working on 1/2 rate convolutional encoding/decoding, can u help me get the logic diagarm for the convolutional encoder for rate 1/2 and constraint length 6, i need this for my project.
