Increasing demand for communication capacity presents important challenges for traditional communication systems. Symentic communication, an emerging technique, emphasizes the transmission of meaningful information rather than raw data, optimizing communication resources for efficient and purposeful exchange.
In a new paper published in Light science and applicationA team of scientists, Professor Ming Tang and Dr. Hua Jong University of Science and Technology, led by Hao Wu, with Doctorate students Zheng Gao and Ting Jiang, has developed a novel optical semantic communication system using multimod fibers. (MMF) to increase data transmission capacity and strength. These scientists briefly present the principles and results of their system:
“We achieved high-dimensional cementic encoding and decoding in frequency domains through taking advantage of intramedal spread in MMFS. By mapping symbols for different frequencies, we demonstrated a seven-fold increase in transmission capacity compared to traditional communication encoding methods. This system also integrates PAM-4 to increase the spectral efficiency, receiving 9.12 bits/s/hertz without any decoding errors. ,
“Beyond improving transmission capacity, we discovered the application in emotion analysis using the IMDB movie review dataset. By encoding the system, by encoding the same symbols for adjacent frequencies, the noise tolerance of the system was effectively improved, the high symbol also facilitates accurate emotion analysis under the terms of the error rate. This approach highlights the ability of MMF-based semantics to increase both capacity and strength in optical communication systems, offering promising applications in bandwidth and noise environment. “He said.
“The innovative method of using MMFS for cementic communication presents a significant advancement in the field of optical communication. The system’s ability to broadcast cementic information directly through optical frequencies with high capacity and strength of the system, it creates a promising solution for future communication technologies. Prize for scientists.
