On Link Misalignment for Underwater Wireless Optical Communications

IEEE Communications Letters, 2012
In wireless optical communications, laser sources have narrow divergence angles and therefore require precisely aligned links, which may increase system complexity and is hard to implement in practice. In the underwater environment, however, the diffuse light field formed at the receiver side due to the scattering property of seawater may reduce the ...
