In this paper, we consider an outdoor visible light communication system, in which on-off keying (OOK) modulation is utilized through an atmospheric turbulence-induced slow-fading channel. A new fast blind detection algorithm is proposed by following the generalized likelihood ratio test (GLRT) principle. In addition, a block coding scheme is presented to solve the unique identification issue and, thus, the error floor problem.
