Many many thanks,

I also realized that the way you call
gr_make_vector_source_s(in_bits,false,K );
is incorrect.
I think you have mis
I also realized that the way you call
gr_make_vector_source_s(in_bits,false,K );
is incorrect.
I think you have misunderstood what this block does.
You should use:
gr_make_vector_source_s(in_bits,false,1 );
or simply
gr_make_vector_source_s(in_bits,false);
and you really don't need the vector2s
In your code the "encoder" block is not connected to any other block...
It should be:
info bits -> encoder -> modulator -> channel -> metrics -> viterbi

Hello ,
I am using conv encoder and viterbi decoder in FHSS-BPSK transceiver.
Below I have pasted encoder-decoder code which is a part of pure C++
application. Problem is encoder input and decoder output do not match.
Can anyone point where i am making mistake ?
Thanks in advance
Ram
