What is MIMO channel matrix?

In MIMO systems, a transmitter sends multiple streams by multiple transmit antennas. The transmit streams go through a matrix channel which consists of all paths between the transmit antennas at the transmitter and receive antennas at the receiver.

What is the channel capacity of MIMO system?

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.

What is channel estimation in massive MIMO?

A channel-estimation-algorithm-based MIMO-OFDM was proposed by [25], where channel state information (CSI) was generated by offline training of the learning network. In MIMO-OFDM systems, for high-mobility scenarios, the deep learning-based algorithm was more robust.

What is channel matrix in digital communication?

A communication channel matrix represents a straightforward five-row/five-column grid designed to map out an array of communication channels used by CMAM programmes for exchanges with the target population.

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].
