What is the channel capacity of AWGN channel?
Show that the channel capacity of an ideal AWGN channel with infinite bandwidth is given by 1.44 S/N0 bps, where S is the average signal power and N0/2 is the power spectral density of the additive white Gaussian noise.
What is the capacity of Gaussian channel?
The capacity of a Gaussian channel is C = 1/2 log(1 + P/N ). In fact, rates R > C are not achievable. The proof parallels the proof for the discrete channel. The main new ingredient is the power constraint.
How is wireless channel capacity calculated?
Capacity is a channel characteristic - not dependent on transmission or reception tech- niques or limitation. In AWGN, C = B log2(1 +γ) bps, where B is the signal bandwdith and γ = P/(N0B) is the received signal-to-noise power ratio.
What is AWGN channel and why it is used?
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.
