No physical channel is perfect; they all introduce noise (e.g., Thermal noise or AWGN - Additive White Gaussian Noise). Communication theory uses probability, , and random variables to model this noise, measure signal-to-noise ratios (SNR), and calculate the probability of bit errors ( Pbcap P sub b Information Theory and Coding
