Haw can I set AWGN Simulink block

Hello, I'm working on a I/Q baseband demodulator and I've to use AWGN block to evaluate performances. I'm using Eb/N0 setting mode and I've some trouble related to values to set. I read from the help about parameters and I would like to explain what I understand (I will use latex notation for formulas): Eb/N0: I set the Eb/N0 in dB; Number of bits per symbol: obviously; Input signal power: I set \frac{1}{T} \int_{0}^T \tilde{s(t)}^2 dt where T is the symbol period and \tilde{s(t)} is the complex input signal; Symbol period: I set T like defined before. My interpretation is correct? Thanks a lot.
