Abstract
To satisfy the application requirement to meet a high data rate and obtain a large coverage in an optical wireless communication system, an optical front-end subsystem () is disclosed in the present invention. The optical front-end subsystem () comprises a first photodiode () with a first active surface area and a second photodiode () with a second active surface area, wherein the second active surface area is larger than the first active surface area. Depending on the received signal strength, either the branch with the first photodiode () or the branch with the second photodiode () is selected to provide an output signal of the optical front-end subsystem (). Receiver diversity is achieved by making use of the first photodiode to support high speed communication and the second photodiode to support large coverage communication.
