In order to realize the stringent requirements of ultra-high reliability and low latency, the data block length needs to be small. However, most of the state-of-art channel codes are designed and optimized for long block length. Analog fountain code (AFC) is a capacity-approaching self-adaptive code on wireless channels with linear encoding/decoding complexity. In this paper, we study the optimization of AFC in the finite length regime. We first analyze the effect of average degree on decoding performance of AFC in the finite length regime. Then, based on the characteristic of weight coefficient in AFC, we proposed a joint design of weight optimization (WO) progressive edge growth (PEG)-AFC algorithm to improve the decoding performance in the finite length regime, named PEG-AFC algorithm. Simulation results show that the proposed PEG-AFC algorithm can achieve lower bit error rate (BER) in a wide range of signal to noise ratio (SNR).","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115496434","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}

Under such scenarios, mobile devices (MDs) that are interested in the same content can be clustered as a group and transmit cooperatively via multiple hops to achieve efficient content distribution. Such multi-hop multicast transmission helps to relief traffic pressure in cellular networks and improve the quality of service for cell edge users. However, it requires careful design of the clustering scheme to ensure delay performance and energy efficiency. In this paper, we propose a multicast clustering algorithm for multi-hop communications. As for each hop, we select a combination of nodes to act as cluster heads (CHs) and multicast the content to a group of next-hop users by jointly considering achievable multicast data rate, remaining operation time and end-to-end delay. In the case of overlapping clusters, we propose a cluster member (CM) reassignment criteria to minimize transmission redundancy. Simulation results show that the performance of our proposed clustering algorithm is competitive in terms of delay and robustness.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116971073","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, existing multibeam HTS is with predetermined beam connection. Considering the mmWave channel is much more sensitive to the weather conditions than the conventional S/C/X band channels, it is important to allocate the limited transmission power to the beams that connect to the ground station in good state. Moreover, due to the huge distance and long propagation delay in the integrated satellite-terrestrial networks, the multibeam HTS can only obtain delayed Channel State Information (CSI) from feedback. In this paper, we model this problem as a Partially Observable Markov Decision Process (POMDP), and propose a power allocation optimization over two identical Gilbert-Elliott beams HTS communication, which can partly mitigate the negative effects of adverse weather conditions. The key thresholds for selecting the optimal power allocation method in the multibeam HTS communications are derived. The effectiveness and potentialities of our proposed scheme is verified through simulation results.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125513132","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}

To improve the reconstruction quality of non key frame which is also called CS frame , the reconstructed key (K) frames are used to generate side information (SI) frames of the CS frames. Therefore, the quality of SI frames greatly affects the reconstruction results of CS frames. However, in conventional distributed compressed video sensing schemes, the quality of SI frames does not achieve the ideal. Because of this, in the current study, a new motion estimation (ME) method called High Efficiency Video Coding motion estimation (HEVC-ME) is proposed for generating more accurate SI to improve the reconfiguration effect of CS frames. In the proposed HEVC-ME, a better estimation result is obtained by performing motion estimation with coding units (CU) of different sizes and using the SATD function as the rate-distortion function, and the generated SI frame retains more detailed information. In addition, we propose an motion estimation (MV) prediction algorithm that further utilizes the motion correlation between adjacent coding units within the video frame on the basis of HEVC-ME. Before the ME, the search starting point is compensated to obtain a more accurate search range to enhance the quality of the SI frame. Experimental results demonstrate that the overall performance of the proposed scheme surpasses that of traditional methods.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117296591","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}
