In the AWGN block there are two parameters: ?Signal to noise ratio? and ?Input signal power, referenced to 1 ohm (watts)?. I just can?t understand why the parameter ?Input signal power, referenced to 1 ohm (watts)? is needed. I think ?Signal to noise ratio? tells everything and only the ratio is important.
