The main purpose of this project was to explain and illustrate the operation principles of MIMO channel technology and how it works, using examples.
In this project, examples of mathematical calculations and self-developed algorithms were used in explaining the various principles of how a MIMO channel could be modelled. Graphs were also presented to give a pictorial image of the various MIMO channel charac-teristics and principles.
The project intended to make the operation of MIMO clear with the help of mathematics and simulations. This is because the operation of MIMO is almost impossible to understand without comprehensive mathematics and simulations. Hence mathematical examples used in this project were simple and easy to follow, thereby giving a clear understanding of how a MIMO channel works.
The results showed that theoretically the MIMO channel technology has the ability to in-crease the capacity of a wireless communication link. It also showed the effects of anten-nas which are important in implementing the MIMO technology in communication systems to deliver the required capacity. The results also showed that, in order to model a MIMO channel, the transmitted training signals have to be linearly independent. After the channel modelling, unknown signals (dependent or independent signals) can be transmitted over the modelled channel.
The project is useful since it gives any reader the basic idea of how a MIMO communica-tion systems works. Many communication systems such as wireless local area network routers are now experiencing the implementation of MIMO technology and this project pro-vides the reader the benefit and idea about MIMO systems.
