Abstract

Water covers more than 75% of the earth's surface in the form of the ocean. The ocean investigation is far-fetched because the underwater environment has distinct phenomenal activities. The expansion of human activities inside underwater environments includes environmental monitoring, offshore field exploration, tactical surveillance, scientific data collection, and port security. This led to increased demand for underwater application communication systems. Therefore, the researcher develops many methods for underwater VLC Visible Light Communications. The new technology of blue laser is a type of VLC that has benefits in the application of underwater communications. This research article investigated the benefits of underwater blue laser communication with recursive OFDM for different water types and discovered the effects of baud rate, bit error rate, and latency which affected several subcarriers of the recursive OFDM that have same characteristics but different environments. The design uses a Xilinx Kintex-7 FPGA evaluation board with high-speed analog daughter card ADC/DAC. It is connected to the terminal blue laser diode as a source of transmitting and receiving signals. There are different experiments doing to find the result and discuss the characteristics of blue lasers in underwater communication for different environments.
