Channel gain in wireless communication

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 are channels in wireless communication?

Wireless channel can be defined as the medium between two end points of a communication system. One end point can be a transmitter (denoted by Tx) that transmits or sends the signal that will propagate through the wireless medium .

How do you increase the capacity of a wireless channel?

As a result, MIMO technology is able to increase the capacity of a given channel while obeying Shannon-Hartley's equation. By increasing the number of transmit and receive antennas, a 2 x 2 MIMO system effectively doubles the maximum data rate of what can be achieved in a traditional single RF channel.

What are the two main effects of the wireless channel?

There are two main types of signal degradation introduced by wireless channels: the first is attenuation and random variation of signal amplitude, and the second is distortion of the signal spectrum.
