Abstract:
We propose and experimentally demonstrate a 10 Gbps PM-QPSK semantic-enhanced LEO-Sat laser system. Experimental results show that the proposed system can save 60% communication overhead and achieve 4 dB receiver sensitivity gain under the same image transmission quality com-pared to the existing systems.
