I need help with a calculating the parameters for AMDSB-TC modulation with AWGN. I have to have SNR = 12 dB. I am not sure how I then calculate the remaining parameters for this.
So
SNR = (A^2*<m^2(t)>*a^2)/E{n}
I am not sure how I get <m^2(t)> and I believe that I need the power spectral density for E{n}, I'm using systemview and it just has density as the input, but i assume it means psd.
So basically my question is how do I know what <m^2(t)> is and what is E{n} in relation to the psd?
