Abstract:
The relatively limited resources, e.g. frequency and power, of wireless communication, necessitate the development of techniques designed to optimize the use of resources for the existing demand. Employing multiple antennas has recently emerged as a viable design choice, as this has the potential to improve the communication rates without having to use more frequency resources. The resulting Multiple-Input-Multiple-Output (MIMO) wireless communication networks need to account for many factors such as shared resources and power constraints, which complicate the design of such networks. Many physical-layer techniques have been developed to counter the effects of interference and noise and to account for power limitations, in order to optimize the performance of MIMO wireless networks under certain conditions. <br /><br /> In this thesis, we explore the application of several physical-layer techniques to improve the performance of MIMO wireless ad-hoc communication networks under realistic operating parameters. A computer model is developed in MATLAB to generate an arbitrary system topology and simulate its performance under a variety of optimization techniques. Performance results are compared for different optimization techniques.
