A geometry-based stochastic model (GBSM) has been received significant attention due to a number of advantages. A GBSM can capture the essential characteristics of propagation channels of interest, and it can be easily applied to different propagation scenarios by considering arbitrary geometries reflecting diverse scattering regions; therefore, it is applicable to modeling of the diverse propagation environments ranging from classical cellular networks to contemporary complex communication systems such as relay networks using multi-element antennas. In this thesis we introduce geometry-based stochastic channel modeling methodologies and analysis of channel statistics for multiple communication environments. By reviewing three important models that have led to the present-day theories of GBSMs from the viewpoints of geometrical and physical representations, we discuss the requirements that must be considered for the development of a GBSM for multiple mobile-to-mobile (M2M) wideband multiple-input multiple-output (MIMO) channel environments. The main objectives of this thesis are: to propose a GBSM based on realistic geometries and tapped-delay-line structure useful for the analysis and simulation of diverse M2M propagation scenarios, and to propose a method to incorporate measured or specified PDPs in the proposed GBSM for reliable and less complex link-level simulations. We believe this thesis is useful for flexible channel model design based on GBSM for contemporary communication systems.
