| description | In this research, texts were sent by pulse width modulation(PWM) in the channel of clean water usingArduino hardware and software for an underwater wireless opticalcommunication system (UWOC). The air bubbles device utilized thedisturbance at different distances from the transmitter source within thechannel of clean water. The total length of the channel is (1) m. In thisstudy, the source of transmitter wavelengths 650 nm was used with thepower of 80mw. The results showed that the received power was 32 mWin the clean water, while when air bubbles pump within the channel ofclean water at 0.2m, 0.5m and 0.8m away from the transmitter source,the received power was 28 mW, 27.5 mW, and 27 mW respectively. Thispaper shows that max. Signal to Noise Ratio (S/N) and min. attenuation(α) in the clean water were (24.637dB) and (3.979dB/m) respectively.The practical results showed that the Symbol Error Rate (SER) in thecase of the air bubbles pump was maximum (0.03) when the value of(S/N) was minimum (23.899). |
