To achieve this purpose, combining Multiple Input Multiple Output (MIMO) architecture with Orthogonal Frequency Division Multiplexing (OFDM) technique is a widely accepted solution and has been implemented in various communication standards. Channel estimation is a critical processing step which is unavoidable in any wireless detection and can significantly impinge the system performance. This paper is tackling such an issue by considering the impact of the pilot symbols design on the LTE-based system performance in terms of BLER. It also proposes new pilot patterns by adjusting both their time and frequency spacing in a first step, then by spatially varying the patterns in a second one. The performance of the proposed patterns is compared to the 3GPP conventional pattern.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132473352","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}

Our work is an attempt to develop user-behavior based power models for smartphones where the premise is the power consumed by the device is directly related to its user's activities which in essence constitute the workload. This can be of great assistance to the designers of smartphones' hardware and software; having a user-driven power model of a device will pave the way for an optimal design. We collected users' related data using an in-house logging tool and a selected set of parameters is identified to develop a Neural Network (NN) based power model. Many trials are conducted in order to identify the suitable NN structure and training algorithm. Results demonstrate that NNs models can provide suitable platforms for studying the energy usage of smartphones.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125249121","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 VSC HVDC tie employing PWM may well represent the ultimate FACTS device. In addition to the control of the active power flow, it can supply reactive power and provide independent dynamic control at its two terminals. The control systems for rectifier and inverter are discussed in DC (HVDC) transmission systems based on three-level voltage source converters. The study involves analysis of active-reactive power capabilities (P-Q envelope) including active power flow and provision of voltage support to AC networks. The transient performance is explored by examining the VSC_HVDC response to external AC faults. Finally, the models and results are presented and tested by simulations using Matlab Simulink and its toolbox SimPowerSystems.","PeriodicalId":405923,"journal":{"name":"2015 International Conference on Electrical and Information Technologies (ICEIT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121257982","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}
