Can u please send me script which can help me .....please I am new to MATLAB Hello Sir,

I think you might have some errors in your results. You have to divide your result by 2 otherwise when you have low SNR your error rate will be above 1. :) https://controls.engin.umich.edu/wiki/images/c/c4/Table_Erf.pdf Best regards, Ovidiu Hy .
