In order to overcome fading in optical wireless channel

such as attenuation and scintillation

this paper introduces the adaptive rate compatible punctured turbo-coded ARQ scheme in optical wireless communication based on analysis of puncturing patterns.Simulations show that the adaptive error control scheme improves the throughput and stability of optical wireless link.Moreover

this paper proposes the rank retransmitting protocol to further improve throughput efficiency under adverse channel conditions according to optical wireless channel characteristic.
