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? How to do that for continuous variables?

The proof that reliable transmission is possible at any rate less than capacity is based on Shannon’s random code ensemble, typical-set 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? Shannon’s Channel Capacity Shannon derived the following capacity formula (1948) for an additive white Gaussian noise channel (AWGN): C= Wlog 2 (1 + S=N) [bits=second] †Wis the bandwidth of the channel in Hz †Sis the signal power in watts †Nis the total noise power of the channel watts Channel Coding Theorem (CCT): The theorem has two parts. 1. ple of the AWGN (additive white Gaussian noise) channel and introduces the notion of capacity through a heuristic argument.

Achieving AWGN Channel Capacity With Lattice Gaussian Coding Cong Ling and Jean-Claude Belﬁore Abstract—We propose a new coding scheme using only one lattice that achieves the 1 2 log(1+SNR)capacity of the additive white Gaussian noise (AWGN) channel with lattice decoding, when the signal-to-noise ratio SNR>e−1. The scheme applies

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.

We then review the channel capacity of the ideal AWGN channel, and give capacity curves for equiprobable -ary PAM ( -PAM) inputs. We emphasize the signiﬁcant differ-ences between the low-SNR and high-SNR regimes. As a The three channels we consider in this text are the binary symmetric channel (BSC), the binary erasure channel (BEC) and the binary input additive white Gaussian noise (BI-AWGN) channel.
