How is MIMO capacity calculated?

MIMO CHANNEL CAPACITY

The theoretical capacity of this system is expressed by the following formula (Telatar, 1999). where, Q = E[xx^H] is the input covariance matrix and E_s is the total transmit power, N₀ is the noise power in each antenna at the receive side.

What is the capacity of MIMO channel?

For example, the MIMO system capacity is approximately 4,8,16,32 times that of the SISO system. The MIMO system generates N parallel subchannels in space through spatial multiplexing, and the total capacity is equal to the sum of all subchannels, which greatly improves the channel capacity.

How does MIMO increase capacity?

MIMO systems exploit multiple antennas at both TX and RX for capacity and/or diversity gain. With both TX and RX CSI, multiple antennas at both transmitter and receiver lead to independent parallel channels. With TX and RX CSI, static channel capacity is the sum of capacity on each spatial dimension.

What is point to MIMO?

Conventional MIMO systems, known as point-to-point MIMO or collocated MIMO, require both the transmitter and receiver of a communication link to be equipped with multiple antennas.
