The paper proposes and analyzes two turbo-coded error control schemes to improve performance of optical wireless communication with long burst error by scintillation and attenuation. Characterization of time parameter of two error control schemes was provided to design. For turbo code + channel interleaving scheme, the paper shows performance of optical wireless communication under various channel interleaving depth. For turbo code + ARQ scheme, simulations show that the feedback delay don′t influence average link throughput, but the feedback delay changes average link delay and probability distribution of transmitting times.
