What is the purpose of AWGN channel?

An AWGN channel adds white Gaussian noise to the signal that passes through it. You can create an AWGN channel in a model using the comm. AWGNChannel System object™, the AWGN Channel block, or the awgn function.

What is AWGN channel give some examples for AWGN channel?

An AWGN channel is the most basic model of a communication system. Some examples of systems operating largely in AWGN conditions are space communications with highly directional antennas and some point-to-point microwave links.

Why is Gaussian noise important?

A first advantage of Gaussian noise is that the distribution itself behaves nicely. It's called the normal distribution for a reason: it has convenient properties, and is very widely used in natural and social sciences. People often use it to model random variables whose actual distribution is unknown.

What is Gaussian noise in communication?

Gaussian noise, named after Carl Friedrich Gauss, is a term from signal processing theory denoting a kind of signal noise that has a probability density function (pdf) equal to that of the normal distribution (which is also known as the Gaussian distribution).
