A remarkable result is that for the AWGN channel the capacity (20.3) can be computed analytically. In particular, for an average power constraint E {| X | 2 }= P , the capacity is achieved for input symbols with a CSCG distribution and increases logarithmically with the signal-to-noise ratio (SNR) P / σ n 2 according to the well-known expression [2]

We then construct a coding and decoding scheme for single-slot capacity that achieves any rate within this capacity region. Channel Capacity - Introduction This webdemo computes the channel capacity of an AWGN channel under various constraints. The channel model is depicted in the graph: Channel Capacity by Shannon - Hartley and Proof of channel Capacity by Shannon - Hartley. Watch later. Share. Copy link.

which results in the channel capacity C = Blog 2(1+γ). (3) The deﬁnition of entropy and mutual information is the same when the channel input and output are vectors instead of scalars, as in the MIMO channel. Thus, the Shannon capacity of the MIMO AWGN channel is based on its maximum mutual information, as described in the next section.

The capacity of the AWGN channel under average transmit power constraint is reviewed from basic information theory in this subsection. For simplicity, we only deal with transmission of one-dimensional signals, but a similar development is made for the two-dimensional case. additive white Gaussian noise (AWGN) channel noise power: N, signal power constraint P, capacity C = 1 2 log (1+ P N) band-limited channel with bandwidth = W C = W log (1+ P N0W) Dr. Yao Xie, ECE587, Information Theory, Duke University 15 In this video we provide a simple yet in-depth explanation to the following wireless communication metrics and terminologies: AWGN, SNR/SINR, Channel Capacity and Spectral Efficiency. There is no constraint on input signal. I don't understand how the professor can directly say the channel capacity is infinite. Don't we need to maximize mutual information between input and output to get the channel capacity?

Unlike the AWGN channel, there is no single definition of capacity for fading channels that is applicable in all scenarios.

I know the capacity of a discrete time AWGN channel is: C = 1 2log2(1 + S N) and it is achieved when the input signal has Gaussian distribution. But, what does it mean that the input signal is Gaussian? Does it mean that the amplitude of each symbol of a codeword must be taken from a Gaussian ensemble?
