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 capacity in AWGN?

The capacity of the AWGN channel at 0 dB SNR is 0.5 bits. per symbol. The error probability of a carefully designed LDPC code in these. operating conditions (rate 0.5 bits per symbol, and the signal-to-noise ratio is. equal to 0.1 dB) with a block length of 8000 bits is approximately 10.

How do you calculate channel capacity?

C = S η log2 e = 1.44 S η . This gives the maximum information transmission rate possible for a system of given power but no bandwidth limitations.

What is capacity of a channel?

The channel capacity, C, is defined to be the maximum rate at which information can be transmitted through a channel. The fundamental theorem of information theory says that at any rate below channel capacity, an error control code can be designed whose probability of error is arbitrarily small.

What is the Shannon's limit for AWGN channel?

or −1.6 dB. This lower bound on E_b/N₀ is known as the Shannon limit.
