The impulse response and frequency response of indoor visible light communication diffuse channels are characterized experimentally in this paper. Both the short pulse technique and frequency sweep technique are adopted for experimental investigation. The iterative site-based modeling is also carried out to simulate the channel impulse response, and good conformity is observed between the experimental and simulation results. Finally, the impact of receiver pointing angles and field of view on the channel 3dB bandwidth is investigated.
