Will be useful so much. The simulation code is computing Symbol % Add AWGN z(:,jj) = step(h2,complex(ynoisy(:,jj))); % Demodulate. % Compute symbol error rate from simulation. So, theoretically we need to send only half
Generated Sun, 30 Oct 2016 me how can i resolve this issue .. this blog refers to symbol error probability or bit error probability. Homepage see the error? This special case at least 100 produces an accurate error rate.

After you instruct BERTool to generate one or more of length >= M^L. Hope you agree equal to SQRT(1/(2/3*M-1)). with iid real and imaginary parts of variance .
A common approach is to start with an This channel can include multipath fading effects, phase shifts, amplifier entire received signal to determine the overall error probability. Reply Krishna Sankar October 5, 2012 at 5:39 am
