Performance of a diffuse optical link may potentially be degraded by temporal dispersions resulting from surface reflections. In order to devise techniques to alleviate the adverse effect of dispersion, an accurate channel model is needed. Obtaining the impulse response (IR) for a given receiver location requires not only consideration of direct path, but also reflections up to nth order. The IR is only valid for a specific location and specific receiver parameters. If a receiver moves, IR has to be recalculated. In this paper, we propose a new approach for characterizing diffuse links that both results in a tremendous saving in calculations and gives more insight on the channel characteristics. The new approach is based on consolidating the dependence of receiver parameters, transmitter parameters, and indoor environment into independent components. Thus, changing one of the parameters of the link requires recalculation of one of these components. The new model is utilized to obtain an accurate profile of delay spread and received power throughout a room.

Exposing engineering students during their education to real-world problems and giving them the chance to apply what they learn in the classroom is a vital element of engineering education. The Embedded Systems course at Princess Sumaya University for Technology (PSUT) is one of the main courses that bridge the gap between theoretical electrical engineering education and the real-world. This paper presents the experience of applying project-based learning to enhance teaching the Embedded Systems course at PSUT. The feedback from students illustrated the effectiveness of this method in enhancing the understanding and the ability of students in applying embedded systems design concepts to solve real-world engineering problems.
