  7. Abstract:
  8. In recent years, communication systems with multiple antennas at the transmitter side and multiple antennas at the receiver side, shortly known as MIMO systems, have attracted a lot of attentions. Capability of these systems to increase the bandwidth efficiency and capacity of communication links has made them the core technology of next generation wireless systems.
    As a first step to design and evaluate the performance of a MIMO system, a suitable channel model which is able to reflect the physical characteristics of the real environment appropriately is essential. Recently, a lot of models have been suggested to investigate MIMO channels, especially correlative models which use relatively a few parameters to describe the channel.
    In this thesis, MIMO correlative channel models are assessed by use of Ray Tracing approach. The mentioned channel models fall into two categories; narrowband channel models, and wideband channel models. First, these models are described in details, and then are implemented using Ray Tracing. The simulation is done in frequency bands of 5.2 GHz and 38 GHz. Our ray tracer has been developed and validated in [42]. The main advantage of using Ray Tracing to simulate these models is the possibility of investigating new frequency bands without major extra costs
