Hi everyone

Could anyone hint me on how to find the SNR for a particular modulation

scheme.

Basically i want to plot the BER v/s SNR curve for gmsk modulation

scheme on a particular link.

I have been successful enough to find BER but cant figure out a way to

find the SNR.

Should I use the FFT way…by calculating the Power spectral density in

matlab and then integrating?..

Or RMS value of the signal can be used (after subtracting the noise)?..

Kindly suggest something if anyone can,

thanks already…
