In satellite communication system, all base stations, base station controllers, mobile switching centers, etc. adopt a common CDMA reference time, namely CDMA system time. The uplink channel is differentiated by PN sequence with orthogonal Walsh code, and is transmitted by the same radio-frequency carrier. The downlink code division physical channel is composed of PN long codes with a length of 242-1, and different phase offsets of the long codes are used to distinguish users. Long codes PNA and PNT are code division channels provided by access channel and downlink traffic channel respectively. The uplink and downlink work in X-band, which meets the speed requirements of 8Kb/s for uplink and 32Kb/s for downlink, and realizes the functions of resisting human interference, narrowband interference, multipath interference, rain attenuation and ranging.","PeriodicalId":142980,"journal":{"name":"2021 2nd International Conference on Computer Communication and Network Security (CCNS)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126182320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to achieve the goal of decentralization, we propose a blockchain-based house sharing platform. Users can directly conduct transactions on the blockchain by running smart contracts. Our scheme guarantees the anonymity of users through commitment scheme and zero-knowledge technology. In order to deal with the problems that may be encountered in reality, we propose a trusted authority to trace malicious users.

First, the theory of neural networks is studied, and its shortcomings are analyzed by the standard Elman neural network. Second, the layers of the feedback nodes of the Elman neural network are improved according to the problems that need to be solved. Then, a network security perception system based on GA-Elman (Genetic Algorithm-Elman) neural network is proposed to train the network by global search method. Finally, the perception ability is compared and analyzed through the model. The results show that the model can accurately predict network security based on the experimental charts and corresponding evaluation indexes.

How to solve the matrix inversion problem has always been a hot spot in precoding research. In order to solve the problem that the Successive-over relaxation (SOR) iteration cannot directly obtain the inverse of the matrix in the massive MIMO system, and the iteration speed is slow, based on SORMI and Chebyshev iteration, we propose a joint precoding algorithm to speed up iteration and obtain better bit error rate performance. It can be seen from the simulation results that, compared with the RZF-SOR and SORMI algorithms, the joint algorithm has a faster convergence rate, and can obtain better bit error rate performance and matrix inversion accuracy with fewer iterations.","PeriodicalId":142980,"journal":{"name":"2021 2nd International Conference on Computer Communication and Network Security (CCNS)","volume":"113 17","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120825780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stacked sparse autoencoder (SSAE) is used to extract high-dimensional features of data, and bidirectional long short-term memory (BiLSTM) is used to classify network traffic.

In this paper, we propose a smart home and cross-cloud-and-edge computing based nursing system (NS). In general, a good NS requires low latency, high stability, and the real-time analysis and response, where the conventional centralized cloud computing based approaches cannot meet those requirements very well. To this end, we introduce a novel distributed joint edge-cloud structure to better satisfy these requirements. Moreover, to deal with the privacy issue, we introduce the differential-privacy (DP) in the NS to protect the healthcare takers’ data privacy. In a word, we propose a privacy-preserving context-aware multi-armed bandit based online learning approach for edge-cloud-enabled NS in smart home. Additionally, our system with a novel top-down expanding tree based structure can support dynamically increasing health care datasets. Extensive simulation results demonstrate that the proposed solution can achieve accurate recommendation results.","PeriodicalId":142980,"journal":{"name":"2021 2nd International Conference on Computer Communication and Network Security (CCNS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128533749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
