How do you calculate channel gain?

The channel gain H of a wireless channel (S,R) is defined by: Y= H X + Z, where X is the signal sent by S, Y is the signal received by R and Z ~ N(0,1) is the noise term.

What is Shannon equation for channel capacity?

Shannon's formula C = 12log(1+P/N) is the emblematic expression for the information capacity of a communication channel.

What is Shannon channel capacity for a noisy channel?

The Shannon limit or Shannon capacity of a communication channel refers to the maximum rate of error-free data that can theoretically be transferred over the channel if the link is subject to random data transmission errors, for a particular noise level.

What happens if bandwidth becomes infinite in a communication channel?

You can easily see the fact that if you have infinite bandwidth B, then you could simultaneously transmit infinite different message signals mk(t) of each having a finite nonzero bitrate Rk (for example by just using a simple FDM scheme) the total of which would add up to inifnite bits per second at once which make ...
