This results in the Fifth Generation (5G) which is expected to meet a manifoldness of wireless communication services [1-2]. However, this mobility can dramatically damage the waveforms orthogonality that is induced in transmission schemes like the Orthogonal Frequency Division Multiplexing (OFDM) systems, which is the main transmission scheme that 4G systems are built on. The deterioration of the waveforms orthogonality in OFDM signals will result in oppressive Inter-Carrier Interference (ICI) and Inter-Symbol Interference (ISI), which leads to significant performance degradation in OFDM systems. In this context, a dynamic waveform construction referred as Ping-pong Optimized Pulse Shaping-OFDM (POPS-OFDM) [3-5] presents an attractive candidate for the physical layer of 5G systems. This innovative approach banks on a non-orthogonal future wireless multi-carrier scheme with a malleable waveform, which would represent an interesting solution that potentially reduces the ISI and ICI and also minimizes the energy spreading. In this paper, we go further by analyzing POPS-OFDM performance when the Tx/Rx waveform support durations are different. This aspect is motivated by the sense to reduce the user equipment's complexity (Tx side) since the mobile phone is limited in terms of power and computation. Simulation results are provided to show that the POPS-OFDM characteristics make this waveform a powerful candidate for 5G systems.","PeriodicalId":314139,"journal":{"name":"2015 5th International Conference on Communications and Networking (COMNET)","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122333650","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 studied technique exploits a preamble of two identical parts and splits the synchronization processing into two stages: a first auto-correlation based coarse stage and a second differential correlation based fine stage. The coarse synchronization aims to roughly localize the preamble position by auto-correlating the received signal using a correlation shift equal to the preamble sub-sequence length. The calculated metric exhibits a plateau that results in an uncertainty in the time detection accuracy. In the second stage and to mitigate the plateau effect, differential correlation is performed using a correlation shift different from the preamble sub-sequence length. The calculated metric provides high sharp peak that results in a very accurate detection. The fine stage is processed over a short interval centered on the coarse time estimate, which reduces the computational load of differential correlation operations. The repetitive structure of the preamble proposed in the IEEE 802.11n standard allows the application of the RC technique on it, using either the first legacy short preamble part or the second legacy long preamble part. Moreover, by choosing a correlation shift equal to the delay used to implement the Cyclic Delay Diversity (CDD) scheme, the RC technique allows to overcome the pseudo-path problem caused by the CDD. As a byproduct, the fractional part of the frequency offset is also estimated through the evaluation of the timing metric at the fine estimate. Simulation results show that, when applied to the IEEE 802.11n signal, the RC synchronization technique provides high detection accuracy that outperforms the considered benchmark.","PeriodicalId":314139,"journal":{"name":"2015 5th International Conference on Communications and Networking (COMNET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130801588","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 aforementioned result characterizes the achievable payoffs for an N-Agent (transmitters in our application) coordination problem with a certain information structure. We then provide an algorithm which exploits the characterization of achievable payoffs by conditional probability distributions to find optimal decision functions for the transmitters. Due to its general nature, the developed framework is conducive for applications to diverse scenarios in wireless communications. In this article, we restrict our attention to the case of decentralized power control in interference channels for different utility functions namely sum-rate, sum-energy and sum-goodput. Our approach has the following salient features: 1) The method proposes optimal power control functions for any given utility function as opposed to ad-hoc solutions for different utilities proposed in the literature, and 2) Noise in the channel estimation is taken into account, thus providing robust optimal solutions.","PeriodicalId":314139,"journal":{"name":"2015 5th International Conference on Communications and Networking (COMNET)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126712174","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}
