57358 融合当前网络编码和多层分布式 LT 码 的优势，提出了一种基于改进双层 LT 码的数据收集策略. Combining the advantages of current network coding and multi-layer distributed LT codes，a data collection strategy based on improved double-layer LT codes is proposed.
57359 该策略采取自适应分组编码机制，避免了因多路径交叉 导致的数据丢失. This strategy adopts adaptive block coding mechanism to avoid data loss caused by multi-path crossover.
57360 仿真实验结果表明，该策略能够在网络连接不稳定的情况下，有效提升数据传输的成功率和吞 吐量. Simulation results show that this strategy can effectively improve the success rate and through- put of data transmission when the network connection is unstable.
57361 针对大规模非静止轨道( NGSO) 通信星座系统间的同频干扰问题，在综合分析传统干扰评价指标的相互转 换关系的基础上，建立了基于链路夹角的干扰分析模型，将通信干扰约束转化为几何构型约束. Aiming at the problem of co-frequency interference between large-scale non-geostationary orbit ( NGSO) constellation systems，we established the interference analysis model of link angle to convert communication interference constraints into geometric configuration constraints based on the comprehen- sive analysis of the mutual conversion relationship of the traditional interference evaluation indicators.
57362 通过卫星选择和链路组合选择定义了系统可用性指标，基于此，开展了基于协作的大规模 NGSO 星座间频率兼容共存研究，并给出了协作模式下 NGSO 星座的工作方式. Furthermore，the system availability index is defined by satellite selection and link combination selection. On basis of this，we carry out some researches on frequency compatibility of collaboration-based large- scale NGSO constellations，in which the working mode of NGSO constellation in cooperation mode is giv- en.
57363 仿真中，选取 OneWeb 和 Telesat 系统实际工作参数，评估了全球范围内系统的可用性. In this simulation，the actual working parameters of OneWeb and Telesat systems are selected to eval- uate the system availability on a global scale.
57364 结果表明，非协作模式下系统平均可用性为 72.82% ，在 27.18% 的时间内系统之间将产生严重干扰，而协作模式下系统平均可用性为 96.00% ，协作模式将大幅提升 NGSO 星座系统之间的频率兼容性. The result illustrates that the average system availability in non-cooperative mode is 72. 82% since the severe interference will occur between systems in 27. 18% of the time，while the average system availability in cooperative mode is 96. 00% ，which means cooperation mode will greatly improve the compatibility of NGSO communication constellation systems.
57365 无线通信信道的特性决定了无线通信系统的性能上限. The wireless channel is the medium in which electromagnetic waves propagate in the air，and the channel characteristics determine the performance of the wireless communication system.
57366 为了解短距离太赫兹信道特性，基于 310 GHz 频段的信道测量，对太赫兹信道的大尺度衰落特性和小尺度衰落特性进行了研究. To under- stand the terahertz channel characteristics in short-distance scenarios，based on the channel measurement in the 310 GHz frequency band，the large-scale fading characteristics and the small-scale fading charac- teristics of the terahertz channel are studied.
57367 分析结果显示，短距离场景下太赫兹信道的路径损耗在 0.2 m 处与自由空间的路径损耗模型结果一致，0.2 m 后实测的路径损耗结果较小，传播条件优 于自由空间. The analysis of the results shows that the path loss of the ter- ahertz channel in the short-distance scenario is consistent with the results of the free-space path loss mod- el at 0. 2 m. After 0. 2 m，the measured path loss results are smaller，and the propagation conditions are better than the free space.
