The analysis of the correlation properties of the proposed channel model is the main objetive of our paper. To achieve this goal, we derive an analytical expression for the space-time-frequency cross-correlation function (STF-CCF) following a geometrical plane-wave propagation (PWP) framework. An important feature of this expression is that it does not depend on a particular arrangement of the interfering objects (IOs) in the propagation scenario. Furthermore, a closedform expression of the STF-CCF is derived for the particular case of the geometrical two-rings model. The analytical and simulation results show that the elements of the MIMO channel matrix are non-wide-sense stationary (non-WSS) random processes both in the time and the frequency domains, as well as pairwise jointly non-WSS both in the time and the frequency domains.","PeriodicalId":190644,"journal":{"name":"2017 IEEE 9th Latin-American Conference on Communications (LATINCOM)","volume":"127 1-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123574718","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 relaying induces a cost for the User Equipment Relays (UER), that should be compensated with a payment from the mobile operator so that UERs accept to offer the service. The problem hence arises for the operator to match cell users and UERs at a reasonable cost and increasing the data rate. In this context, we consider the requirements of truthfulness, budget feasibility and acceptance of online scenarios to compare ON algorithm, which considers all constraints, with other three algorithms that were not built to respect all of them, Hungarian, Threshold and Online Weighted Knapsack (OWK). We observed that ON algorithm is the best in terms of execution time; however, it does not scale well considering the number of matched edges, requiring modifications in its selection criteria. In addition, we noticed that OWK algorithm has appealing properties and, if it were modified to be truthful and to reduce its complexity, it would present the best results.","PeriodicalId":190644,"journal":{"name":"2017 IEEE 9th Latin-American Conference on Communications (LATINCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129123713","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 will allow the service provider to develop less cost multi-standard devices that rely on the same master clock compatibility and with the same time-frequency grid representation of the LTE-A. The main characteristic of generalized frequency-division multiplexing (GFDM) modulation is low out-of-band (OOB) emission, accomplished by using flexible pulse shape filtering in the timedomain of individual subcarriers. In this paper, first we focus on the integration of GFDM in the time-frequency grid of the LTE-A system and then we analyze the impact of “Better than Nyquist” pulse shaping filters on OOB emission and symbol error rate. We consider different “Better than Nyquist” pulse shaping filters that were originally introduced in single-carrier modulation schemes to reduce the sensitivity to symbol timing error. By using the results available in the literature, the performance achieved by “Better than Nyquist” pulse shaping filters is compared to that achieved by conventional Nyquist ones. The concept of the wavelet, based on the Meyer auxiliary function, along with pulse shaping filter will be also addressed. The results are presented for 16-QAM in the case of transmission over AWGN, time-varying frequency flat, and static frequency selective fading channels. Monte Carlo simulations are shown in order to validate the accuracy of the analytical expressions.","PeriodicalId":190644,"journal":{"name":"2017 IEEE 9th Latin-American Conference on Communications (LATINCOM)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125509666","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}
