However, in spite of its practical relevance, the impact of the channel's non-stationarities on the performance of the vehicular communication systems (VCS) has barely been investigated, and is therefore not fully understood. To increase the knowledge on such important subject, we present in this paper a comparative performance analysis of six channel estimation techniques for VCS based on the IEEE 802.11p Standard, namely, the Least Squares (LS), Spectral-Temporal Averaging (STA), Modified STA (MSTA), Constructed Data Pilots (CDP), Frequency Linear-Averaged Data Pilot (FLDP), and Time-Domain Reliable Frequency-Domain Interpolation (TRFI) estimation techniques. Using a novel simulation framework, we evaluate the estimators' performance in terms of their bit error rate (BER) for the case when the propagation channel fulfills the wide-sense stationary uncorrelated scattering (WSSUS) condition, and also for the case when such condition is not met. The obtained results show that the estimation techniques that apply a joint time-frequency interpolation (STA, FLDP, and TRFI) are considerably more sensible to the channel's non-stationarities than the techniques that only interpolate in the time domain (MSTA and CDP).","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"22 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":"125144171","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 will allow the society to be fully mobile, integrated and connected to anything, anytime, anywhere. The vehicle-to-everything (V2X)scenarios integration with the 5G networks is unavoidable, allowing the cars to be connected to the new radio (NR)technology. Among the next-generation vehicle networks challenges it is the guarantee of on-board entertainment service delivery quality. For this purpose, this article evaluates vehicular traffic with Internet-based video services requests, using a 5G network approach based on software defined networking (SDN). Specified features and requirements of the international mobile telecommunications for 2020 and beyond (IMT-2020)systems have guided the proposal. Simulations were performed through the Network Simulator ns-3. The simulations adopted enhanced mobile broadband (eMBB)use cases, employing millimeter wave (mmWave)communications. The two main metrics - transfer rate, and transmission delay - were analyzed and compared. The results show satisfactory performance to the V2X communications stringent requirements, when adopting millimeter waves on the future 5G networks.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"30 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":"115901880","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 is done through the primary ideas of the 6Genesis Flagship Program (6GFP), a recently formed Finnish academic and industrial consortium aiming at developing key enabling technologies for 6G. 6GFP is an eight-year large-scale research initiative set to ultimately develop, implement and test key enabling technologies for 6G. Motivations, visions, trends and expectations for 6G are first discussed to set the ground for further development. Four main research areas are proposed as the starting point, encompassing not only wireless communications but also computer science, electronics and material science as well as applications and services. The paper provides an in-detail list of technical topics going to be studied in this program, and in general, worth considering for everyone planning to develop beyond 5G technology. The paper also shed some light on how the research will be implemented, showing the logic and relationships between the research areas, discussing already selected promising enabling technology for 6G, as well as envisioning how the proof-of-concept of the developed system will be carried out. An existing state-of-the-art 5G network will be used as the starting point for developing and testing the novel concepts and technologies created in the program.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"89 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":"129676354","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 algorithm is implemented on a basic structure of an octagonal printed antenna which includes a search process based on finding an optimal solution for the effective length of a H-Shaped Notch filter located in the patch. The filter position in conjunction with the effective length determines the frequency ranges that will be rej ected and can be adjusted over the entire operational range of the antenna. In this case, it is proposed to rej ect the frequency bands for IEEE 802.11a and WLAN-HIPERLAN / 2 from 5.1 to 5.9 GHz by applying SA WOA, obtaining an effective filter length of approximately 18.6454 mm and positioned around 12.5269 mm from the power line to ensure an optimum rejection with a center frequency of 5.5 GHz. The dimensions for the optimized printed UWn $B$ octagonal antenna are 30 mm ⨯ 35 mm, with a bandwidth of3.1 to 12 GHz and a return loss less than −10 dB throughout the UWB frequency range except in the optimized rejection range. The proposed SA WOA algorithm uses a correlation-based cost function between the fitness agent and a previously defined response pattern, resulting in a shorter computational time to achieve best parameters providing a high structure precision as well as high performance level.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"61 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":"131244904","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}
