It is extremely challenging to design the modulator for THz communications.In this paper, an electrically controlled THz metasurface was designed and fabricated based on the phase transition characteristic of Vanadium Dioxide (VO2). It can switch between two resonant states with a large difference in transmittance. The experimental results show that the transmittance of perpendicular incident THz wave reaches to the highest at 0.31 THz. When the applied voltage is increased from 0 V to 8 V, the transmittance significantly decreases to the lowest value at 0.41 THz. The modulation depth can be up to 59% in the entire band of 0.2-0.6 THz. This work is of great significance for the research and development of THz modulators.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"52 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120817022","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}

Furthermore, to reduce the use of radio frequency chains, hybrid beamforming for MIMO system is proposed. In conventional method, in order to optimal the uplink sum rate, exhaustive search algorithms are commonly used to select the best codeword for analog beamforming. However, exhaustive search algorithms also cause too much complexity to be implemented in engineering. In this paper, an iterative sub-optimal algorithm is firstly proposed to avoid the computation of matrix inversion. Moreover, we propose a data-driven method based on RBF-NN of analog beam codebook selection to further reduce the complexity. Specifically, with training data coming from samples of the terahertz channel, the analog beam codebook selection problem is considered as a multiclass-classification problem. Using the dataset, we built a statistical classification model via RBF-NN method which can select suitable analog beams for each user, with low complexity and near optimal sum rate. Analysis and simulation results reveal that, compared with the conventional method, as long as the training data are sufficient, the proposed method reduce complexity by several orders, with near-optimal performance.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123978564","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}

However, the communication distance in THz networks is constrained by the severe path loss in THz frequencies and the limited transmission power, which results in the network deployment issue. In recent years, researchers have shown a growing interest in the utilization of adaptive transmission power as well as multi-connectivity THz communication. In this paper, a multi-beam on-demand power allocation medium access control (MAC) protocol for Multiple-Input Multiple-Output (MIMO) THz communication in distributed wireless networks is presented. The proposed dual-band protocol relies on a multi-beam antenna structure, which utilizes the limited transmission power to achieve multiple concurrent THz connections by applying the proposed distance-aware power allocation scheme and redesigning the frame formats. The simulation results demonstrate the relationship between the number of beams with SNR threshold and average node distance. The results concluded by comparing the total throughput of the proposed multi-beam network with classical single-beam network show that the proposed protocol maximize the THz channel utilization and achievable throughput.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124466171","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}

However, due to the resource scarcity and the diversity of slice requests, how to allocate resources efficiently to maximize the long-term reward of the infrastructure network is a challenging issue. In this paper, we model the resource allocation problem as a semi-Markov decision process (SMDP), which is defined by state space, action space, reward and transition probability distribution. The reward function jointly considers the total income, the cost of available resource and the utilization of the total resource for the infrastructure network. Not focusing on one step decisions reward, we apply the Bellman equation to obtain long-term reward by accumulating. Then we exploit value iteration algorithm to determine the resource allocation scheme according to a certain state in such a way that the long-term reward can be maximized. Extensive simulation results show that the proposed SMDP can achieve a superior performance compared with the existing heuristic methods.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123716876","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}
