Abstract: As indoor Optical Wireless Communications (OWC) is characterized by enormous spectrum source, lower power need, immunity to interference caused by other Radio Frequency (RF) wireless devices, it has attracted an increasing attention in the field. However, due to multipath transmission, it is hard to obtain satisfactory uniform signal quality at the receiving terminal even for locations within the same room. A genetic algorithm based optimization scheme was proposed as a candidate approach for OWC to reduce the variability of the received power. And the simulation results based upon the use of a commercially available detector with the field of view of 50 degree show that the dynamic range of received power can be reduced to 34.6% against the peak optical power from 50.3% while the impact on illumination function is negligible.
