The transmit power and half power semi-angle (HPSA) of LEDs as well as receiver's field of view (FOV) affect the performance of indoor visible light communication systems. In this paper, a novel linear programming (LP) method is proposed to optimize transmit power of LEDs. System performance with different HPSA and FOV is also investigated. Simulation results show that a significant improvement of illumination and communication quality as well as a remarkable reduction of power consumption is achieved after the proposed LP optimization. What's more, the influence of various HPSA and FOV on VLC system is found to be double-sided.
Keywords:visible light communication; power allocation; linear programming
