The information theory concept that is related to channel capacity is mutual information. If $X$ is the transmitted signal and $Y$ is the received signal, the mutual information between the two is due to the channel. | |

Your paranthetical is correct, though- high SNR implies that the noise is lower than the transmitted signal (actually, it implies that it is higher than the received signal, but close enough). | |
