Abstract
We propose and evaluate a novel configuration that employs a multibeam transmitter in an optical wireless system. Such a configuration borrows attractive features from diffuse and line-of-sight systems, resulting in great robustness and ease of use. A line strip multibeam transmitter placed on the communication floor is proposed to produce a line of diffusing spots on the middle of the ceiling. The results associated with the new structure show that a receiver SNR improvement of about 3.8 dB can be achieved compared to the conventional diffuse configuration. Other geometries including a diamond-shaped spot geometry and a uniform spot geometry are also considered. Power distribution, received pulse shapes, and a comparison with the conventional diffuse link are outlined. SNR results show that the proposed geometries are very attractive.
