Inspired by this, in our proposed cooperative radar-communication system, the base station (BS) signal is also used for detection at the radar, while the IRSs are utilized at the radar and BS to enhance the signal transmission and receiving simultaneously. A successive IRS phase shift optimization method is proposed to get the suboptimal phase shift with low computational complexity. The convergence performance and quantization of IRS phase shift are discussed. The simulation results verify the effectiveness of utilizing the IRS and BS to improve the detection performance regarding the detector’s SNR.","PeriodicalId":335240,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132414337","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}

Age of information (AoI) is a metric used to measure the freshness of information. Existing works typically focus on AoI analysis in static transceivers or mobile scenarios that do not consider interference between transmitters. In this paper, we explore the AoI in MMSNs, including the channel fading, path loss and consider network topology, spatial interaction queue, as well as shared spectrum interference problem. We deduce the upper and lower bounds of AoI in this scenario and obtain the relationship between AoI and mobile speed, spatial density and channel access probability through simulation. We find that the average AoI decreases as the average speed of the jammers increases with preemptive last-come-first-served (LCFS) discipline. It can provide reference for obtaining the optimal AoI of system.","PeriodicalId":335240,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"299302 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116577626","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 main focus of research has been on training a single network when addressing the problem. In our work, we explore a dual network approach. We propose a brain-inspired complementary dual network model for continual learning that comprises a fast learner and a slow consolidator. The fast learner first adapts to a new task seen only once, and the slow consolidator distills the new task information using knowledge distillation from the fast learner. The two networks are trained in an alternate manner. To consolidate the learning of a new task with the learning of past tasks, we employ a small memory of each task for replay during the training of the slow consolidator. In addition, we incorporate a context-based gating mechanism on the slow consolidator, and empirically prove its positive impact on the performance of the proposed model. We show the improved results of the proposed model on several classification datasets.","PeriodicalId":335240,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124903353","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 the outdoor scene, location fingerprint is still at the stage of constructing a fingerprint database due to the vast region and its large data, so its locating speed needs to be faster. In the view of the slow speed, this paper proposes optimized K-means algorithm by ICFSFDP algorithm to process the outdoor fingerprint database, aiming to greatly increase the locating speed without sacrificing the accuracy of locating. In order to verify the performance of the algorithm, the standard propagation model is applied to calculate the sampling point’s reference signal received power (RSRP), and universal Kriging algorithm is used to interpolate the database, ensuring the authenticity of outdoor environment simulation. The result shows that the locating speed of outdoor fingerprint database can be greatly improved without decreasing accuracy, after being processed by I-CFSFDP optimized K-means.","PeriodicalId":335240,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125161559","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 combination of a pair of fiber Bragg gratings and a MSC contributes to the wavelength and transverse-mode switching. Owing to the mode separation feature of the MSC and the dual-branch laser configuration, laser modes could be controlled with ease by tuning intra-cavity loss inside the dual-branch laser cavities. We observe a dual-wavelength Q-switched operation with simultaneous LP01 and LP11 modes output successfully.
