Introduction - If you have any usage issues, please Google them yourself
the study of communication systems the classical (ideal)
additive white Gaussian noise (AWGN) channel, with statistically
independent Gaussian noise samples corrupting data
samples free of intersymbol interference (ISI), is the usual
starting point for understanding basic performance relationships.
The primary source of performance degradation is thermal
noise generated in the receiver. Often, external
interference received by the antenna is more significant than
thermal noise.
