“…Here, the transmitter transmits a light pulse and creates a specific time slot, while the receiver detects the pulse, calculates its position, and reforms the signal to the original pulse [35]. PPM consumes lower energy but it has lower bandwidth efficiency.…”

Underwater optical wireless communications (UOWC) have gained a considerable interest during the last years as an alternative means for broadband inexpensive submarine communications. UOWC present numerous similarities compared to free space optical (FSO) communications or laser satellite links mainly due to the fact that they employ optical wavelengths to transfer secure information between dedicated point-to-point links. By using suitable wavelengths, high data rates can be attained. Some recent works showed that broadband links can be achieved over moderate ranges. Transmissions of several Mbps have been realized in laboratory experiments by employing a simulated aquatic medium with scattering characteristics similar to oceanic waters. It was also demonstrated that UOWC networks are feasible to operate at high data rates for medium distances up to a hundred meters. However, it is not currently available as an industrial product and mainly test-bed measurements in water test tanks have been reported so far. Therefore, extensive research is expected in the near future, which is necessary in order to further reveal the "hidden" abilities of optical spectrum to transfer broadband signals at higher distances. The present work summarizes the recent advances in channel modeling and system analysis and design in the area of UOWC.

“…The following results are mainly based on (Meihong, Xinsheng & Zhangguo, 2009) (Meihong, Xinsheng & Fengli, 2009). For OOK demodulation format a threshold is used to compare the received voltage to decide "1" or "0".…”

“…Table 3. Transfer rate versus implementation complexity from (Meihong, Xinsheng & Fengli, 2009) 2. the Phase Shift Key (PSK) modulator generates an in phase signal for digital "1" and an out of phase signal for a digital "0". In this case the PSK demodulator are complex since the different coherent demodulation are needed to compare the current phase with the previous phase and it can be inefficient for power-constrained devices.…”

“…Most of the underwater VLC research focuses on digital modulation techniques such as On-Off keying (OOK), pulse position modulation (PPM) for a reliable communication system [10]. As a communication medium, underwater is very harsh and complex environment, so amplitude based modulation techniques are susceptible to intensity variation due to scattering and other effects.…”
