Submission doc.: IEEE a Kookmin University May 2015 Slide 2 Kookmin University Response to 15.7r1 CFA: OCC Application in Light house-to-Ship Communication Yeong Min Jang

Submission doc.: IEEE a Kookmin University Slide 3 May 2015 Contents  Scenario of Light house-to-ship using OCC  Challenging issues  Our demonstration  Other considerations  Conclusion

Submission doc.: IEEE a Kookmin University Slide 4 May 2015 Scenario of Light house-to-ship using OCC Unidirectional OCC Lighthouse LED Driver module High power LED to blink data at far distance Data Rolling shutter camera with Zoom module Rolling shutter picture Asynchronous decoding Data Zoom module Far-distance of transmission required. Asynchronous communication scheme is needed.

Submission doc.: IEEE a Kookmin University Slide 5 May 2015 Why using Zoom module without Zoomwith Zoom Experimental test Higher SNR can be achieved => more far distance of transmission

Submission doc.: IEEE a Kookmin University Slide 6 May 2015 Challenging Issues Lighthouse transmitter Light tail (Reflection by water surface) Noise sources  Low SNR due to far-distance; Various noise resources  Light reflection and wave motion

Submission doc.: IEEE a Kookmin University Slide 7 May 2015 Our Demonstration Zoom module Zoom module is required (instead of increasing power) to achieve far-distance transmission

Submission doc.: IEEE a Kookmin University Slide 8 May r1 (Various) Our demonstration  Achieved Distance: 100m (using Zoom)  Achieved Link rate: 120bps

Submission doc.: IEEE a Kookmin University Slide 9 May 2015 Estimation of 1km transmission 1 km 100m 15cm x 15cm 12VDC/15W Real LED lamp Camera position Size: 1.5m x 1.5m LED panel: 1500W

Submission doc.: IEEE a Kookmin University Slide 10 May 2015 Other considerations Variable FOV Light house Buoy  Link switching to get seamless link  Variable FOV to transmit variable range

Submission doc.: IEEE a Kookmin University Slide 11 May r1 (Various) Conclusion  Need PHY to support asynchronous communication for unidirectional system  Need to have a link switching functionality  Consider far-distance transmission (up to km distance) such as scenario of light house-to-camera.
