Thank you Wayne King. I did get benefit from your code. i want to ask please about finding the bet error rate for such a code. How can i determine the decision regions, so that i can then find the bet error rate?
Can i consider the originally sent data as a training data and resend data again and consider it and a test data and use them to find the bet error rate?
Thank you very much. Kawther Hamad,
