However, this information is insufficient when the users share the same scattering environment. In this paper, we propose a novel strategy by exploiting the user mobility. Due to limited scatterers around the users, we first investigate the channel sparsity and derive the corresponding angle-Doppler frequency domain channel power spectrum (AD-CPS). We then propose a method to mitigate the pilot contamination through aligning the AD-CPSs. Compared with the existing works, we further demonstrate the effectiveness of the proposed scheme in supporting more orthogonal pilots when the interfering users exhibit different moving patterns. Simulations verify the superior performance and show that the proposed scheme can serve as an additional decontamination mechanism for the UL pilots in massive MIMO systems.","PeriodicalId":119131,"journal":{"name":"2018 IEEE Global Conference on Signal and Information Processing (GlobalSIP)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127606314","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}

This model is based on the measurement campaign that our team conducted at Boise Airport and Boise State University. The close-in reference path loss and floating-intercept path loss models with both statistical and stochastic approaches are investigated for these environments. The measurements were collected at several different locations in line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios using high gain directional antenna. The path loss exponent and shadowing factor are determined based on the measurement results and compared with recent work at this frequency. Both the stochastic gradient descent algorithm and the statistical least-square technique are used to analyze the floating-intercept path loss model. The results show that the path loss exponents in the outdoor scenarios are higher than the indoor environment due the RF noise caused by the sunny and dry climate in the Boise area. Finally, a good agreement is found between the measurement results and the prior work results in presented in the literature.","PeriodicalId":119131,"journal":{"name":"2018 IEEE Global Conference on Signal and Information Processing (GlobalSIP)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129023889","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 demand response, dynamic pricing schemes are believed to have significant potential to fully exploit the flexibility of shiftable energy consumptions. Most existing work on dynamic pricing schemes, however, falls short on consideration of price discrimination over different types of consumer groups. In this work, we propose a bilevel game theoretical Stackelberg model between a price-making utility company (a leader) and price-taking consumer groups (followers) in a discriminated dynamic pricing environment. We show under price discrimination producer surplus is monotonically increasing as energy consumption capacity of consumer groups increases. Numerical simulation validates our theoretical analysis and also shows that without price discrimination the social welfare may decrease against the energy consumption capacity of consumer groups. Moreover, social welfare can be higher under price discrimination.","PeriodicalId":119131,"journal":{"name":"2018 IEEE Global Conference on Signal and Information Processing (GlobalSIP)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116907595","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 real time applications, latency performance is a crucial metric in fog computing. In this paper, we consider a sequential decision-making problem for computation offloading with unknown dynamics in which a mobile user offloads its arrival tasks to associated fog nodes (FNs) at each time slot. The queue of arrival tasks at each FN is modeled as a Markov chain. In order to provide satisfactory quality of experience, the network latency, which is directly associated with the queue condition, needs to be minimized. Taking advantage of reinforcement learning, the sequential decision-making problem is formulated as a restless multi-armed bandit problem. We construct a policy with interleaved exploration and exploitation stages, which achieves a regret with sub-linear order. Both analytical and simulation results validate the effectiveness of the proposed method in dealing with sequential decision-making problem.","PeriodicalId":119131,"journal":{"name":"2018 IEEE Global Conference on Signal and Information Processing (GlobalSIP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131091923","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 recent years, extensive research has been conducted on using social sensing as a platform to detect critical events and emergency situations such as natural disasters, criminal activities, and power outages. In this paper, we focus on detecting real-time power outages using social sensing by investigating different predictive models, preprocessing techniques and feature extraction methods. The investigation shows that multi-layer perception neural network outperforms other popular predictive models. The paper proposes a real-time situational-awareness mechanism to detect the ongoing power outages and extract useful information for power outage management. In the proposed framework, for temporal analysis, a modified approach of Kleinberg’s burst detection algorithm is proposed to ensure the prompt detection of power outages. This study paves the way for future investigation and innovation in efficient real-time event detection using social sensing.","PeriodicalId":119131,"journal":{"name":"2018 IEEE Global Conference on Signal and Information Processing (GlobalSIP)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128296141","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}

Four propagation channels in Ka band are considered and implementation constraints are modeled. The conclusions highly depend on the channel type. For open rural and high speed train (300 km/h) scenarios, 5G NR PHY may be used as is. Higher speed scenarios (aero 1000 km/h) can benefit from the 5G NR mode that allows very short symbols (although this mode is only allowed for large band).

We first demonstrate that for a fog network with different kind of nodes, balancing the energy relies on a combinatorial optimization that is solved using graph theory. We propose a transformation of the transshipment graph problem to formulate an optimization problem that we solve with linear programming (LP). We show the possibility of balancing and extending the battery life of the whole network based on cooperation between nodes without jeopardizing individual nodes’ battery life. We use both, emulation and real scenarios to test our optimization algorithm.

A business is incentivized to reduce its power consumption, but accurately predicting the timing of peak demand charges is nontrivial. In this paper we present a decision framework based on predicting the day-ahead likelihood of peak demand charges.
