This project explores the development of a multiple input multiple output (MIMO) simulator using ray tracing techniques. This project gives an overview of ray tracing techniques, beamforming, MIMO channel models and MIMO systems. It explains the ability of MIMO systems to offer significant capacity increases over traditional wireless systems, by exploiting the phenomenon of multipath. By modelling high frequency radio waves as travelling along localized linear trajectory paths, they can be approximated as rays, just as in optics....

Sensor arrays are used to overcome the limits of simple and/or individual
conventional sensors. Obviously, it is more complicated to deal with some issues
related to sensor arrays, e.g. signal processing, than the conventional sensors. Some of
the issues are addressed in this book, with emphasis on signal...
Multiple simultaneous beams exist when an array of N elements is connected to a beamformer with 1M beam ports, where N and 1M may be different. Multiplebeam systems have many uses: in electronic countermeasures, in satellite communications, in multiple-target radars, and in adaptive nulling, for example. The last application uses adaption in beam space as it avoids several serious difficulties that arise with adaption in array space. (Mayhan, 1972).
