Pls define with simple examples in the following...

What is MIMO? why we go for in communication.

benifits of MIMO?

what is difference between MIMO and multicarrier system?

What is Spatial multiplexing?
 

Re: MIMO

Give simple defination for understanding ....
 

Re: MIMO

it's a system that uses multiple antennas at the transmitter and the receiver side to create a radio link.

 

Re: MIMO

We use this technology in telecommunications, because we want to obtain more and more data rate.
The benefits of MIMO is increasing data rate without spreading allocated bandwidth.
MIMO consists several transmitting and receiving antennas, hence there are several information flows. Transmission of all flows fulfils on the same frequency unlike multicarrier systems.
Spatial multiplexing is a method of segmentation one information flow with high daata rate on M flows with lower rate in transmitter, transmission, reception and incapsulation all this M flows again in one flow on receiver.
