A visible-light communication utilizing LED has many advantagies such as visibility of information, high SNR
(Signal to Noise Ratio), low installation cost, usage of existing illuminators, and high security. Furthermore,
exponentially increasing needs and quality of LED have helped the development of visible-light communication.
The visibility is the most attractive property in visible-light communication system, but it is difficult to ensure
visibility and transmission efficiency simultaneously during initial access because of the small amount of initial
access process signals. In this paper, we propose an efficient resource allocation scheme at initial access for
ensuring visibility with high resource utilization rate and low data transmission failure rate. The performance
has been evaluated through the numerical analysis and simulation results.
