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.

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 channel capacity theorem?

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 Shannon theorem for channel capacity?

The Shannon capacity theorem defines the maximum amount of information, or data capacity, which can be sent over any channel or medium (wireless, coax, twister pair, fiber etc.). What this says is that higher the signal-to-noise (SNR) ratio and more the channel bandwidth, the higher the possible data rate.
