What is meant by additive white Gaussian noise?
Additive white Gaussian noise (AWGN) is a basic noise model used in information theory to mimic the effect of many random processes that occur in nature. The modifiers denote specific characteristics: Additive because it is added to any noise that might be intrinsic to the information system.
Why is AWGN called white noise?
White – This refers to the idea that the noise has the same power distribution at every frequency. Therefore, white noise has a constant Power Spectral Density (the measure of a signal's power compared to frequency) across all frequencies.
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 objectâ„¢, the AWGN Channel block, or the awgn function.
What is AWGN in 5G?
AWGN which is Additive White Gaussian Noise plays a crucial role in determining the performance of wireless communication systems. Therefore, this concept is important to understand if you are working on 5G NR, LTE or WLAN.
