The outer precoding design is based on the lower bound of the signal-to-leakage-plusnoise-ratio (SLNR) and then the SLNR-based design problem is reduced to a trace quotient problem (TQP) in Rician channel. An iterative algorithm is proposed to achieve the optimal results for the TQP. Numerical results illustrate that the proposed method has better sum rate performance for the HAP Massive MIMO systems and lower computational complexity compared to the existing outer precoding design for the Rician channel.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129758112","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 paper, resource partition and message transmission schemes with geo-based resources allocation (GRA) for inter-platoon communication are proposed. Based on that, received signal-to-interference-plus-noise ratio (SINR) is analyzed. The expressions of success transmission probability and average energy efficiency (EE) are obtained by using the tool of stochastic geometry. In particular, the optimum transmit power that fulfills a given minimum success probability constraint while maximizing the average EE is calculated. Mathematical results show both success probability and average EE can be improved by adjusting the transmit power.

This creates issues in Handover performance, where it becomes difficult to manage when and to which base station should a mobile user swap to during a connection without significant losses in performance, due to the large quantity of cells in one space. On the other hand, systems like Automatic Neighbour Relations, present in 4G Long Term Evolution configurations, mostly consider Handover statistics to decide the best neighbours, which is insufficient due to potential problems with signal coverage and load balancing which it cannot answer to. In this paper, an implementation of a cloud-based automated pixel-based neighbour identification system for cellular networks using Amazon Web Services is presented, wherein it generates high quality ranked Neighbour Cell Lists by utilizing cell topology and associated signal strengths in a map defined by a Pixel grid, which itself is built from data provided by the network’s Operations Support System. It’s completely technology agnostic and it’s incorporated as a package in the Metric Software as a Service ecosystem, facilitating network planning assessment by measuring the cells’ coverage overlap, and initializing neighbour lists. The proposed method can be used as a starting point for ANR, since it’s capable of building a neighbour cell list in some seconds for a new network deployment, which can be then optimised by ANR mechanisms later with an operating network.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115417569","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 facilitate EH and information processing simultaneously, we consider the power-splitting (PS) protocol at the multiple-antenna relay. Unlike the existing OS strategy, where the OS is only exploited at the source-to-relay or the relay-to-destination link, our proposed OS-based on the AS (OS-AS) scheme can achieve much transmission performance. Moreover, in the framework of an amplify-and-forward relaying network, the closed-form analytical expressions for the outage probability and ergodic capacity are derived in general signal-to-noise ratio (SNR) regime. Simulation results validate the accuracy of the proposed scheme, and also demonstrate that the proposed OS-AS strategy outperforms the other benchmark schemes.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120809226","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}

Traditional Global Structure from Motion (SfM) pipeline and learning-based pipeline from the recent techniques have been analyzed. Based on the pipeline, the methods are categorized into three groups: learned features and matching, learned relative pose estimation, and learned absolute pose estimation. Since multiple sensors are used in many applications, sensor fusion techniques including image information, have been briefly reviewed in this paper as well. Furthermore, the paper discusses challenges in these methods and concludes learned features and matching is the more competitive method for indoor localization.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129064755","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}

It is based on two types of Drive Test (DT) data: dedicated and scanner modes. It proposes an algorithm that jointly analyses both data sources, whereas the dedicated data is used as a network performance reference, the scanner data evaluates the radio resources for a possible optimization. Thus, under-performance regions representing areas of low coverage are firstly identified, and optimized either through logical parameters or physical ones. The proposed algorithm focus on logical parameters optimization, more specifically handover parameters. It introduces a novel cost function to evaluate the performance of new configurations, based on three fundamental pillars; signal strength level maximization, ping-pong handover effect reduction and parameter stability assurance. The results are promising as they were developed and validated using real Mobile Network Operator (MNO) data and in certain scenarios a signal strength level improvement of more than 30% has been attained while minimizing the number of handovers and ping-pong effects.","PeriodicalId":298927,"journal":{"name":"2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132398468","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}
