For a time-invariant AWGN channel with received SNR γ, the maximizing input distribution is Gaussian, 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

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?

We find the structure of the capacity achieving input distribution, under the average power constraint. We find the capacity achieving input for the large interference to noise ratios.

1, C ! P N0 log2 e bits per second Dr. Yao Xie, ECE587, Information Theory, Duke University 13 Thus the channel capacity for the AWGN channel is given by: C = 1 2 log ⁡ ( 1 + P N ) {\displaystyle C={\frac {1}{2}}\log \left(1+{\frac {P}{N}}\right)\,\!} Channel capacity and sphere packing Edit So if we take the familiar voice grade telephone channel with 35 dB SNR and 3000 Hz BW, we find the AWGN capacity C is about 34.8 kbps which is a familiar number. To get from there to bits/symbol we divide by the symbol rate, which must be something close to 3000 giving 11 bits/symbol.

Example 1.1 Thebinarysymmetricchannel(BSC) showninFigure1.2transmits On the Capacity of the AWGN Channel With Additive Radar Interference Sara Shahi , Daniela Tuninetti, and Natasha Devroye Abstract—This paper investigates the capacity of a commu-nications channel that, in addition to additive white Gaussian noise, also suffers from interference caused by a co-existing radar transmission. Despite the well-known result that capacity is achieved by a continuous (Gaussian) pdf for the PC-AWGN channel, our results demonstrate that a finite-support input PMF can always approach the capacity to less than 0.01 bits as long as log 2 of the input cardinality is 1.2 bits above the PC-AWGN capacity, or alternatively the entropy of the input PMF is 0.9 bits above the PC-AWGN capacity. The capacity of binary input additive white Gaussian noise (BI-AWGN) channel has no closed-form solution due to the complicated numerical integrations involved. In this letter, a simple upper bound to evaluate the capacity of BI-AWGN channel is presented.
