Design and Study of Cognitive Network Physical Layer Simulation Platform
Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014 Cognitive radio technology has received wide attention for its ability to sense and use idle frequency. IEEE 802.22 WRAN, the first to follow the standard in cognitive radio technology, is featured by spectrum sensing and wireless data transmission. As far as wireless transmission is concerned, the availability and implementation of a mature and robust

International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 The indoor visible light propagation characteristics are simulated and analyzed using the method of SBR/Image (shooting and bounding ray tracing/Image). A good agreement is achieved between the results simulated and the results given in published literature. So the correctness of the method has been validated.
