Paralleler Simulator für die Berechnung von Raumechos

Room impulse response simulation determines the channel transfer function of indoor wireless optical communication systems. The simulator calculates time-dependent distributions of optical power spectral density. A drawback of current implementations is its poor execution speed. In this research project a special-purpose computer architecture for the simulator is developed to increase performance. New Radiosity-based algorithms are designed to reduce computational complexity of the simulator. The algorithms are parallelized and mapped onto a multiprocessor. The prototype implementation is a scalable hypercubic multi-DSP based on digital signal processors TMS320C40. Experimental evaluation shows a significant speedup of this specialized computer architecture.
