Hello,
I have tried to simulate the performance of an OFDM system using QPSK a rate 1/2 convolutional code and a Viterbi decoder at the receiver. The problem I face now is after plotting the results, I come up with a funny graph that doesn't look anything like the theoretical result.
Here's an attachment of the MATLAB image i obtained.
Can anyone possibly tell me where I have gone wrong in this code?
