Abstract :
This paper studies the coded performance of optical wireless communication systems employing subcarrier PSK modulation through atmospheric turbulence channel. Convolutional code and Viterbi decoding are used for optical wireless communication system with subcarrier BPSK and a comparable system with fixed-threshold OOK. It is shown that an interleaver can help to handle bursty errors and improve the coded BER performance.
