Interference coupling cooperative suppression method for wideband carrier communication based on improved variational mode decomposition by Dandan DONG, Ning SUN

“…The interference coupling of power line broadband carrier communication aggravates the frequency domain tailing between subcarriers, reduces the sensitivity of suppression methods, and the communication quality is poor.Therefore, a cooperative suppression method of interference coupling of power line broadband carrier communication based on improved variational modal decomposition was proposed.Based on the channel characteristics of power line broadband carrier communication, a communication channel model with multipath propagation and Doppler effect was established, the communication signal was simulated, the original signal was preprocessed by using the improved variational modal decomposition algorithm, and the suppression problem was transformed into a variational problem.At the same time, the signal was expressed in the discrete form of unconstrained variational problem.The variational problem was continuously updated to complete the separation and processing of the signal, and realize the cooperative suppression of communication interference.The experimental results show that the proposed method has low bit error rate, small frequency offset, and practical application value.…”

Design and implementation of unmanned surface vessel long-distance communication system by Xue LI, Haiju HU, Weiping WANG, Yankun CHEN, Bing ZHENG, Chao DONG

“…Unmanned surface vessel (USV) long-distance communication has important use in marine survey operations.The design and equipment development of USV long-distance communication system were carried out from both shore-side communication equipment and boat-mounted communication equipment, and the broadband and narrowband tests of the communication system were carried out in Wanshan and Yellow Sea with the assistance of tethered UAV to conduct communication range test for the whole system.The test results show that when the shore-side communication equipment is raised 129 m, the broadband communication can reach 45 km, when the shore-side communication equipment is raised 180 m, the narrowband communication can reach 50 km, and the communication quality is stable and reliable, meeting the long-distance communication needs of USV.…”
