Data transmission maximum distance in underwater wireless optical communication channel (UWOCC)
with pulse-code intensity modulation (PCM) is estimated. The aim of the work is to investigate the possibility
to use Reed-Solomon codes for increasing real time video data stream transmission distance, without increasing
radiation power. The article presents bit error rate (BER) modeling depending on the range for
various values of electrical bandwidth. The calculations were carried out for UWOCC without correcting
coding, as well as with Reed-Solomon codes. The use of Reed – Solomon codes is shown to provide a gain in
maximum range of not less than 38 meters with channel bandwidth of 100 MHz, not less than 32 meters with
channel bandwidth of 1 GHz, and not less than 30 meters with channel bandwidth of 10 GHz. The spread in
maximum length values lies in the range between 7 and 13 meters depending on electric channel bandwidth.
Key words: underwater optical wireless communication channel, optical wireless communication, free space optical channel, mathematical model, underwater communications systems.
