What is MIMO system capacity?
The capacity C in (9) is also referred to as the error-free spectral efficiency, or the data rate per unit bandwidth that can be sustained reliably over the MIMO link. Thus, given a bandwidth of W Hz, the maximum achievable data rate over this bandwidth using the MIMO channel is simply WC bps.
How channel capacity is going to affect the MIMO channel?
The data analysis shows that the distributed MIMO system can significantly increase the system’s channel capacity. The system’s capacity is also closely related to whether the antennas are evenly placed. When the antennas are evenly placed, the capacity is increased and the distribution is more uniform.
How does MIMO calculate SNR?
You can also consider the SNR of the MIMO system for a particular transmission method. You select a precoding vector at the transmitter and a combining vector at the receiver. This will effectively turn the channel into an SISO channel and you can now compute the SNR.
How does MIMO work?
MIMO is effectively a radio antenna technology as it uses multiple antennas at the transmitter and receiver to enable a variety of signal paths to carry the data, choosing separate paths for each antenna to enable multiple signal paths to be used. By using MIMO, these additional paths can be used to advantage.
How does 4×4 MIMO work?
4×4 MIMO, sometimes referred to as 4T4R, uses four antennas to establish up to four streams of data with the receiving device. With four spatial streams established the data payload is divided across all four antennas and transmitted over the same frequency band.
What is MIMO channel?
MIMO stands for Multiple-In Multiple-Out, referring to the fact that when a packet is transmitted into the channel it transmitted on more than one antenna and when it comes out of the channel it is received on multiple antennas.
What is MIMO fading channel?
The MIMO Fading Channel block filters an input signal using a multi-input/multi-output (MIMO) multipath fading channel. This block models both Rayleigh and Rician fading and employs the Kronecker model for modeling the spatial correlation between the links.
