4343	为了克服大规模 MIMO 的技术瓶颈——上行链路导频污染，与现有盲导频去污染中系统参数同时设计的方法不同，提出了系统参数的分层设计方法，	In order to overcome uplink pilot contamination, the technical bottleneck of massive MIMO, and differentfrom the existing parallel parameter design strategy for blind pilot decontamination, a hierarchical parameter design me-thod was proposed,
4344	指出不同的系统参数对最终接收信号样本协方差矩阵谱精确分离的作用是不同的，即具有不同的优先级。	which points out that different system parameters have different effects on the exact spectrum separa-tion of the sample covariance matrix of the received signal. In other words, different parameters have different priority.
4345	然后，发现要实现谱分离，期望信号的功率并不一定要高于干扰功率，两者之间的差异才是决定因素。	Next, it was found that to achieve spectral separation, the power of the desired signal didn't have to be higher than the in-terference, and the difference between the two was more important.
4346	更进一步地，在导频序列长度小于基站接收天线数这种更实际的场景下，首次给出了一种数值算法同样能实现上述的精确谱分离。	Furthermore, in a more practical scenario where the pilot sequence length was less than the number of base station receiving antennas, a numerical algorithm was given forthe first time to achieve the above-mentioned exact spectral separation.
4347	实验仿真证明，由于分层的参数设计保证了渐近谱的精确分离，所提方案比现有的盲导频去污染方案更适合实际应用。	Since the hierarchical parament design ensuresthe exact separation of the asymptotic spectrum, the results show that the proposed scheme is more suitable for practical applications than the existing blind pilot decontamination.
4348	针对大规模、超密集部署移动互联网和物联网引发的精确频谱共享需求，基于区块链技术提出联网海量个人无线设备构成频谱设备网络：	To meet the requirement of the precisely spectrum sharing triggered by large-scale and ultra-dense deploymentof mobile internet and internet of things, a framework based on blockchain technology for networking the massive per-sonal wireless devices to form the Internet of spectrum device (IoSD) was proposed.
4349	频谱管理服务器、移动基站、个人无线设备形成云计算与边缘计算相结合的频谱设备网络架构，以频谱数据获取、频谱区块添加、频谱数据传输、频谱数据采集的激励构成了基于区块链的频谱设备网络的基本运行机制，通过感知节点共识融合、验证节点共识验证、簇头节点共识确认，在一定置信度下的假设检验判断是否有恶意感知节点发动伪造频谱数据的拜占庭攻击。	The architecture of cloud with edgecomputing was proposed as the architecture of IoSD, which consists of spectrum management server, mobile base station,and personal wireless devices.The mechanism of spectrum data acquisition, spectrum block appending, spectrum datatransmission, and spectrum sensing incentive, consist of basic operational mechanism of IoSD.The distributed consensus mechanism, including fusion consensus among sensing-nodes, verification consensusamong checking-nodes, and confir-mation consensus among head-nodes, was applied to determine whether the spectrum data was falsified by the Byzantineattack of malicious sensing-nodesunder the hypothesis test of certain confidence.
4350	仿真结果表明分布式共识机制在防御恶意感知节点伪造频谱数据的拜占庭攻击上的有效性和可靠性。	The simulation results show the effec-tiveness and robustness of proposed distributed consensus mechanism in preventing spectrum sensing data falsificationby the malicious nodes.
4351	针对当前异构调度模型仅从空间或者时间特性进行建模设计，缺少对时空特性的综合考虑且存在动态性和异构性不够均衡的问题。	At present, most heterogeneous scheduling models were only designed from the perspective of space or time,without comprehensive consideration the characteristics of time and space, and there was a problem of insufficient bal-ance between dynamics and heterogeneity.
4352	为使拟态云服务系统的动态、异构和冗余特性能够平衡互补，提出一种基于优先级和时间片的执行池调度算法，该算法基于执行池相似性指标进行优先级预排序，结合时间片等策略进行方案调度。	In order to balance the dynamic, heterogeneous and redundant characteristicsof the mimic cloud service system, an executor pool scheduling algorithm based on priority and time slice was proposed,which performed priority pre-sorting based on the executor pool similarity indicator, and scheduled the program in com-bination with strategies such as time slice.
