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 is MIMO channel capacity calculated?

MIMO CHANNEL CAPACITY

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. In Eq. 3, the mean is taken over the random channel.

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.

When the MIMO channel is correlated the capacity of channel *?

It is known that the channel capacity in a MIMO communication system depends on the number of transmit and received antennas, the signal-to-noise ratio, the channel state, and the autocorrelation or covariance matrix of the transmitted signal vector [1].
