Multi-line Multi-Spot Diffusing Indoor OW Channel with A 7-Detectors Diversity Receiver
نویسندگان
چکیده
We evaluate the optical gain achieved in an indoor optical wireless (OW) channel when increasing the number of branches of the angle diversity receiver from three to seven. Simulation is carried out for five different spot diffusing geometries as to compare the systems' performance when the square-base three branch angle diversity receiver is replaced by a hexagonalbase and seven-branch design. The channel performance is evaluated in terms of signal-to-noise ratio (SNR) where the results are computed and plotted for various receiver positions. Further channel gain of up to 5 dB at worst links is also shown when the diversity receiver's signals are all combined using Maximum Ratio Combining (MRC) instead of only selecting the one branch with best SNR.

Evaluation of An Indoor OW Channel Employing A Mobile Multi-line Multi-Spot Diffusing Transmitter and A Seven Detectors Angle Diversity Receiver
Multiple narrow beams' transmitters have been shown to improve the performance of the indoor optical wireless channels by a remarkable higher signal-to-noise ratio (SNR) and a lower signal delay spread over the conventional diffuse transmitters, especially at weak locations (when the transceivers have the highest separation distance). Further performance improvement is attained through the use ...
متن کاملAn Indoor Optical Wireless System Based on Different Spot Diffusing Geometries and A Diversity Receiver
Abstract: We evaluate the performance of a multi-beam transmitter system in an indoor environment where a diversity receiver is employed. The system’s performance is evaluated under four new multi-line spot diffusing geometries and is compared with the performance of a single line of diffusing spots and with the conventional diffuse system (CDS). The performance is analysed under the influence ...

We evaluate transmission link performance for a Multi-Spot Diffusing Configuration (MSDC) for indoor wireless optical LANs. MSDC utilizes a multibeam transmitter and a composite receiver consisting of 7 narrow field-of-view (FOV) branches. Numerical evaluation is performed for two values of the receiver FOV corresponding to the cases when at least one or two diffusing spots are covered by a bra...

متن کاملAdaptive Moblile Spot Diffusing Transmiter for an Indoor Optical Wireless System
An adaptive approach is used to adjust the transmit power of each beam in a line strip multi-beam optical transmitter based on information about the quality of the received signal due to each spot. The system assumes a feedback link between the optical transceivers. Diversity detection is employed to combat the degrading effect of the background noise in the channel with a 7detectors angle dive...
