Abstract Details

2006, Doctor of Philosophy, Ohio State University, Electrical Engineering.
A new full wave methodology and a well-established ray-tracing method are employed for indoor wireless communications channel modeling. The full-wave method, referred to as array decomposition-fast multipole method (AD-FMM) for indoor simulation, is based on the finite element-boundary integral formulation. A key feature of this technique is the use of domain decomposition methods to efficiently model repeatable components such as bricks, chairs, tables, etc. This leads to significant memory reduction allowing the simulation of realistic structures with different antenna locations to predict the statistical profiles of the received signal strength. These profiles are subsequently used to evaluate the bit error rate (BER) for specific digital modulation schemes. The method is also employed to predict the statistical channel capacity for multiple input multiple output (MIMO) systems via the complementary cumulative distribution function. This dissertation also exploits an established ray-tracing electromagnetic (EM) simulation tool, and measurements for indoor channel characterization for wireless applications. Specifically, measurements are conducted for indoor environments to validate the channel model obtained using ray tracing tools. Such ray-tracing channel models are appropriate for 4th generation 60~GHz communication systems.
