Reducing the signaling overhead and enhancing the coverage are two important targets. To reduce the signaling overhead, UL grant free transmission is considered, where one user equipment (UE) transmits data directly on one resource unit within the preconflgured resource set without eNB's scheduling. Repetition is the baseline method for coverage enhancement. To achieve efficient transmission, different repetition levels are configured for one UE and UE selects the repetition level for the transmission based on its measurement results. On the eNB side, eNB blindly decode the incoming data by assuming different repetition levels. In this case, eNB may successfully decode the data in earlier time before the repetition ends due to the inaccurately under-estimated channel estimation on the UE side and then performs the HARQ-ACK feedback earlier than the UE's expectation. In this case, unnecessary retransmissions happen at UE side due to the miss detection of the HARQ-ACK. Unnecessary retransmissions lower the spectral efficiency and consume more power on the UE side. To avoid the early termination on the eNB side, we propose to use repetition-level specific sequence to scramble the data. Simulation results show by using the proposed method, the unnecessary retransmissions are totally eliminated and the spectral efficiency is improved by around 30% and the power saving is improved by around 35%.","PeriodicalId":228625,"journal":{"name":"2018 20th International Conference on Advanced Communication Technology (ICACT)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122237855","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}

When people visit the sites later, however, they can rarely experience these contents again. The objective of this study is to exploit these photos and videos from filming sites together with their shooting locations and attitudes in order to provide users with AR (Augmented Reality) tourism services. Users will be able to experience as if they are at the site just at the time of filming. We designed and made an external attachable device for DSLR (Digital Single-Lens Reflex) cameras to log shooting locations and attitudes. We also implemented syncing software and defined data formats to integrate these data with photos and videos. We implemented mobile AR tourism apps for iOS and Android platforms. We adopted FAST (Features from Accelerated Segment Test) algorithm with additional modification for AR visualization of photos in mobile environment. We adopted Ferns algorithm, histogram specification and OpenGL texture mapping for AR visualization of videos with better performance. These apps and the results of this study were evaluated at actual filming sites of several dramas, and the survey of many filming staffs was conducted for feedbacks. The results of this study could be applied many other fields concerned with multimedia contents.","PeriodicalId":228625,"journal":{"name":"2018 20th International Conference on Advanced Communication Technology (ICACT)","volume":"86 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131959213","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 this case, the parenteral administration may be divided into mucosal administration methods such as ocular mucosal administration, nasal administration, sublingual administration and rectal administration, and injection administration methods such as intravenous injection and subcutaneous injection, and skin administration method.

Moreover, the capacity of multi-hop wireless network can be substantially increased via multiple radios tuned to non-overlapping channels. However, the channel allocation, network interface cards assignment and routing selecting remain challenging due to the interference of the neighboring transmissions. These three problems have proved to be a NP-hard problem. Previous studies separating the routing selecting from the channel allocation, instead of considering the three problems as a whole, cannot get the overall optimal solution. In this work, we employ an improved Multi-Objective Genetic Algorithm to optimize the channel allocation, interface assignment and the routing selection, so as to minimize the overall network interference. The proposed algorithm includes two parts: 1) dynamic genetic mutation based on diversity measure; and 2) elite preservation based on ideal points. In order to eliminate the impact of illegal solutions, a new individual encoding method is proposed. In addition, an interference model taking into account the effects of channel separation and the traffic of neighbor links is applied to evaluate the quality of the interference of the network. Finally, a fitness function is defined to obtain the best search results. Simulation results show that our improved Multi-Objective Genetic Algorithm can reduce the interference and cost of total network compared to the standard Genetic Algorithm.","PeriodicalId":228625,"journal":{"name":"2018 20th International Conference on Advanced Communication Technology (ICACT)","volume":"16 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132644161","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}

Nevertheless, there are two main drawbacks: rank deficiency and processing delay. The first drawback can be solved by performing systematic network coding, in which sender transmits all uncoded packets in the first phase and coded packets in the second phase. The processing delay still remains in practical communication system and multimedia content delivery. In this paper, we propose a practical incremental network coding for application of multimedia content delivery over multi-hop network. We implement the proposed scheme using Raspberry Pi as transmission node and evaluate performance in terms of throughput and the attainable video quality (i.e., peak signal-to-noise ratio). The results demonstrate that our proposed incremental network coding outperforms conventional network coding schemes.","PeriodicalId":228625,"journal":{"name":"2018 20th International Conference on Advanced Communication Technology (ICACT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122528711","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}
