The methods used for analytical evaluation is matrix analysis and nonlinear least squares estimation theory. The approach for experimental validation is a software-defined radio (SDR) transceiver working on National Instruments (NI) Universal Software Radio Peripheral (USRP) hardware with LabVIEW software, performing transmission, reception and processing of signals. Presented solution was validated in static scenario and achieved position errors of several meters depending on the number of range measurement trials. The resulting error was substantially affected by synchronization uncertainty due to network organization of transceiver stations and measurement processing unit. However, in the conclusion we can state that joint processing of range measurements with trial results accumulation can substantially improve positioning accuracy and it was experimentally validated with software-defined radio testbed.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125832567","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}

Employing OFDM over high speed optical transmission systems requires large hardware resources due to computational-intensive operations such as full-parallel FFT implementation. The proposed 256-point FFT/IFFT adopts 32-paths parallel architecture with mixed radix-23 and radix-25 algorithm to reduce large number of complex multipliers. With this architecture, 256 full parallel data signals can be divided into eight sequential groups. Each group, composed of 32 parallel signals, is pipeline-processed. As a result, the hardware resources for full parallel 256-point FFT operation can be reduced to as much as those of 32-point FFT resource plus 32-path 8-point single-path delay feedback (SDF). The proposed FFT architecture is implemented with field programmable gate array and integrated in 12 Gbps, 64-QAM encoded real-time optical OFDM system. The implementation result shows that an 86% complex multiplier reduction can be achieved in comparison with full parallel architecture. The attained error vector magnitude (EVM) is approximately up to -32 dB for 64-QAM OFDM signals.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"154 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128655714","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 support customers in decision making, some sites collect and provide user reviews on products. However, contents of the user reviews are too abundant for customers to analyze them in a short period of time. The automatic analysis of reviews is important to provide users with valuable information about goods of any category. The objective of this research is to improve the usefulness of reviews for consumers. This research focuses on an opinion dictionary as a collection of specific keywords and key phrases. This opinion dictionary models a standardized better review to extract patterns of trustworthy reviews. In this study, a simple corpus of three different categories of goods is composed. It consists of noun and adjective keywords. This research is successful to obtain essential features and relations among three different categories in the opinion dictionary. Moreover, this opinion dictionary will be applied to supervised learning methods, such as a support vector machine to create a review evaluation system. The findings from this study can contribute to assist users' decisions to evaluate reliable and useful reviews.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132399535","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}

ETRI (Electronics and Telecommunications Research Institute) has been designing and developing a new moving wireless backhaul system, Mobile Hotspot Network (MHN) system, which can support over 1Gbps data rate services for mobile group vehicles running at high speed up to 500km/h such as KTX (Korea Train Express) express train. In this paper, the methods to adopt the iterative receiver algorithm are introduced to improve MHN system performance. One of the main characteristics of MHN system is to apply multi-flow structure, which may cause interferences between two data stream, therefore, this can degrade system performance. However, due to multi-flow characteristic, we can apply the iterative receiver algorithm. In this paper, we showed the possibility to improve system performance by applying iterative receiver algorithm. Currently, we have developed the MHN test-bed system and had a goal to demonstrate the real time performance of the MHN system in the outdoor environment by Feb., 2016. Outdoor demonstration will be shown at line 8 subway in Seoul, Korea.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133747272","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 estimation of the CSI assists the eNB scheduler to properly allocated radio resource to the UE. The SRS transmission can be also be used to support downlink beamforming. The sub-frame in which SRS is transmitted by any UE within the cell is signaled via cell specific broadcast signaling, there are 15 possible sets of subframe in which SRS may be transmitted within each radio frame. The SRS is based on the extended zadoff-chu sequence and transmitted in the last SC-FDMA symbol of an uplink subframe, the SRS transmitted by the UEs are multiplexed in the time and freq. domain through configuring SRS periodicity SRS, frequency comb pattern, and SRS bandwidth. Different sets of UE-specific sounding signals are independently allocated for SRS transmission, including transmission bandwidth, frequency comb pattern, cyclic shift. In this paper, transmission subframe, bandwidth, freq. comb pattern, for it suggests ways to reduce the measurement performance and HW complexity of the UE between the Sounding RS separated by a Cyclic shift value and Timing offset measurement method.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116165284","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}
