Exploring MIMO Technology for Underwater Communication
Oceans cover approximately 71% of the Earth's surface, making their exploration and resource utilization strategically significant. Communication technologies play a pivotal role in oceanic research and resource management. Due to the low attenuation characteristics of blue-green light in the 450-550 nm wavelength range and its inherent advantages of wide bandwidth, high capacity, and fast transmission rates, Underwater Wireless Optical Communication (UWOC) has emerged as a promising solution for real-time, high-speed data transmission.
However, challenges such as complex underwater environments and the limited bandwidth of optical devices constrain UWOC's communication range and transmission rate. Multiple-Input Multiple-Output (MIMO) technology, which transforms single-stream data into multi-stream data for parallel transmission, has garnered attention for its potential to enhance UWOC performance. MIMO alleviates the adverse effects of absorption, scattering, and oceanic turbulence, extending the communication distances.
The awarded paper provides a comprehensive analysis of MIMO technology in UWOC, covering topics such as:
Selection of light sources and multi-source channel modeling methods.
State-of-the-art advancements in non-imaging and imaging MIMO-UWOC technologies.
Spatial diversity and multiplexing techniques in non-imaging MIMO-UWOC.
Typical experimental setups and prototypes of MIMO-UWOC system.
The paper also recommends the future research directions of MIMO-UWOC.
