Abstract
Optical wireless communication systems usually adopt on-off keying (OOK), binary pulse position modulation (BPPM), and binary phase-shift keying (BPSK). In this work, the scheme of systems based on a turbo code of OOK, BPPM, and BPSK is proposed, and the three different iterated maximum a posteriori (MAP) algorithms of turbo code are deduced. To use the turbo code based on different modulated formats over optical wireless channels we deduce the formula of an atmospheric channel signal-to-noise ratio versus the atmospheric visibility. Simulations show that the turbo code based on BPSK is well suited for optical wireless communication systems.
