Abstract:This project focuses on the practical application of techniques regarding spatial multiplexing. Spatial multiplexing is implemented by estimating the channel matrix using a least squares approximation. The obtained channel matrix is decomposed using a singular value decomposition. The resulting singular values and singular vectors for various scenarios are related back to the principles of spatial multiplexing. A simulation environment is created to make the techniques more insightful and to provide a baseline performance on what to expect from practical scenarios. Using standard building materials and basic RF equipment, a setup is constructed to do practical experiments. Experiments are carried out to characterize the behavior of the transceiver system in both a controlled environment as well as in practical scenario's. Another aspect of this research is the robustness of the system against interference. Using MUSIC a profile is made from possible interferers within the surroundings. This profile is then used to create a spatial filter which can be used to suppress the influence of the interferer. This technique is implemented to view the performance of such a filter for both simulations as well as a practical scenario.
