What is channel Estimation in MIMO?

MIMO. systems use multiple antennas to transmit and receive. signals. Channel Estimation means to estimate channel. parameters from the received signal.

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].

How data rate is increased in MIMO techniques?

Transmitting two or more data streams in the same bandwidth multiplies the data rate by the number of streams used. In addition, MIMO in the 11n standard permits two signal-free adjacent 20-MHz channels to be bonded together into a single 40-MHz+ channel, which can provide even higher data rates.
