Geometry Scenarios for Optical Camera Communication Application
This document, submitted by Yu Zeng from China Telecom to IEEE 802.15 Working Group, focuses on geometry scenarios for Optical Camera Communication (OCC) applications. It includes simulations for indoor office and hall environments, detailing room dimensions, transmitter and receiver locations, and impulse responses for different scenarios.
