We have a problem in doing 16-QAM soft decision demapping program.
The problem might be the Euclidean distance calculation.

Can any one help me with the code, concerning demodualtion and decoding codes to do the program.So that in the end I can get the simulation to exam the performance of the system.

Thank you

It might be. Or, based on the information you provided, the problem
might be you not wanting to bother doing your own work at all and are
hoping that someone will do it for you. I'm not saying that *is* the
case, but the information you gave us does not allow us to distinguish
that case from the possibility of a mere problem calculating Euclidean
distances.

Why don't you post the section of code that calculates Euclidean
distances, and we'll have a look at it and see whether it calculates
them correctly or not.
