AWGN. All wireless receivers suffer from thermal noise which is a function of absolute temperature and bandwidth of the receiver. This noise is added to the received signal and makes detection of weak signals a major challenge. Just to given you an idea typical GSM receivers have a noise floor of -113 dBm.

Additive White Gaussian Noise (AWGN) The performance of a digital communication system is quantified by the probability of bit detection errors in the presence of thermal noise . In the context of wireless communications, the main source of thermal noise is addition of random signals arising from the vibration of atoms in the receiver electronics.

This channel model is used to evaluate the difference between a LOS model and a channel model including fast-fading effects. Hence, the AWGN results can be seen as reference measurements. Definition of Additive White Gaussian Noise in the Definitions.net dictionary. Meaning of Additive White Gaussian Noise. What does Additive White Gaussian Noise mean? AWGN channel model.

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. The following examples use an AWGN Channel: QPSK Transmitter and Receiver and General QAM Modulation in AWGN Channel.

The AWGN channel is a well-known model to indicate line of sight (LOS) conditions. This channel model is used to evaluate the difference between a LOS model and a channel model including fast-fading effects.

When considering coded modulation schemes for the AWGN channel, two main practical limitations prevent achieving channel capacity, namely the need to use a finite constellation and coding inefficiencies. Constellation shaping was given new impetus in recent works by Böcherer et al., which combined probabilistically shaped ASK constellations with LDPC coding. One open question is how far their

AWGN stands for Additive WhiteGaussianNoise. Actually this name itself has all the detailed information in it as follows.

Each of these letters hold so much significance and has to be looked into separately.
