GSFIM uses both spatial domain and frequency domain to encode bits through indexing. In GSFIM, information bits are mapped through antenna indexing in the spatial domain, subcarrier indexing in the frequency domain, and M-ary modulation. GSFIM can offer higher rates using fewer transmit radio frequency (RF) chains and better performance compared to conventional MIMOOFDM. In this paper, we address the problem of low-complexity encoding and detection of large-dimensional GSFIM signals. The proposed encoding procedure exploits the low complexity computation of combinadics in combinatorial number system. This allows `on-the-fly' computation of GSFIM encoding maps. For detecting GSFIM signals, we propose a low complexity detection algorithm based on a multi-stage message passing approach. The proposed low complexity encoding/detection algorithms allow practical implementation of large-dimension GSFIM systems.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124264053","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}

Much research has focused on coexistence cognitive networks- where secondary users are vying for spectral \"white space\" when primary users vacate a licensed frequency band. This work will instead focus on an \"open spectrum\" regime, where there are no primary or secondary users, but all are provided equal access to the available band. Many cognitive medium access control (MAC) layers have been proposed to regulate the use of spectrum in a spectrum sharing regime, but most require the use of a common control channel (CCC) for information exchange. Additionally, while there is much research focusing on the spectrum sensing problem (detecting the presence of unused bands), the problem of spectrum recognition (determining the band of a signal of interest) has not received as much attention. We propose a new modulation scheme, frequency envelope modulation (FEM), that enables the creation of an open, cognitive ad hoc network. This network uses distributed spectrum sensing and information sharing to dispense with the need for a CCC. The effect of FEM on the physical layer is analyzed, as well as the network configuration time using FEM. We show that knowledge sharing via FEM reduces configuration time exponentially compared to uncoordinated scanning.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"35 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120978542","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 means a substantial spectral efficiency increase, which must be achieved while maintaining or even improving the power efficiency. To overcome the necessity of using inefficient linear HPA in typical communication systems, this paper addresses the use of the LINC technique for power amplification, since it employs grossly NL HPA that are simpler and much more energy efficient than the linear ones. However, this technique's efficiency is harshly damaged for signals with a large PAPR, as for systems employing high order spectral efficient modulations and/or close to Nyquist bandwidth limiting pulse-shaping, due mainly to the LINC signal separation and power combining procedures. However, given that any M-ary constellation can be split as a sum of several OQPSK signals, a new MM method is proposed for OQPSK signals with bandwidth close to Nyquist, that limit both maximum and minimum envelope excursions of the signal without spreading its spectrum. This method is also shown to improve the transmitter's resilience to small gain and phase imbalances between the LINC's amplifiers. The proposed scheme can play a critical role on the upcoming 5G, since arranging several units of the proposed transmitter in an array/parallel configuration has the potential to simultaneously achieve the required high power and spectral efficiency.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124884093","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}

Where there is overlapping coverage of multiple Radio Access Technologies, with no cooperation between them, a vehicle can use the different technologies simultaneously to enhance performance and improve resilience. This paper proposes an uplink Multi Interface Scheduling System (MISS) that incorporates intelligent interface selection, located at an intermediate shim layer on the user side, to achieve efficient bandwidth aggregation, or lower delay. The data can be sent on multiple technologies simultaneously or separately based on user preference and required performance. Rather than finding the best alternative amongst different technologies, this paper's algorithm aims to find all the available networks that can meet multiple criteria. Simulation has been carried out to determine the performance of the system in the presence of a range of different service types. The simulation results show that safety critical traffic can be prioritized in terms of throughput and delay where the resources are insufficient for all the services. This algorithm is ideally suited to vehicular networks, particularly where delivery of safety traffic is an essential requirement.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122422137","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}
