However, it has proven to be a challenging task due to the presence of Kerr effects, which have largely been regarded as a major bottleneck for enhancing the achievable information rates in modern optical communications. In this work, the optimisation and performance of digital nonlinearity compensation are discussed for maximising the achievable information rates in spectrally-efficient optical fibre communication systems. It is found that, for any given target information rate, there exists a trade-off between modulation format and compensated bandwidth to reduce the computational complexity requirement of digital nonlinearity compensation.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114230415","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 scheme, the best path is selected among multiple branches and a multiple-antenna source (S) communicates with a multiple-antenna destination (D) via the relays of the selected path. Each relay is equipped with multiple transmit and receive antennas. It is assumed that there is no direct link between S and D. Moreover, S and all relays employ SSK modulation to transmit information bits and each relay in each path follows the decode-and-forward principle. A closed-form approximate symbol error rate (SER) expression for the proposed SSK system is derived. Furthermore, an asymptotic SER performance analysis is also performed. The analytical results are verified through Monte Carlo simulations. It is shown that the proposed multi-hop SSK system with path selection outperforms conventional multihop M-PSK system with path selection in terms of the SER performance for especially high data rates and sufficient number of receive antennas at the receiving nodes.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"49 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":"115098447","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}

At the same time multipath transmission in conjunction with transmit/receive signal combining being its corner stone can be incapable to exploit available spatial diversity. Hence it is vital to understand to which extent the parameters of the MIMO system can be optimized in order to raise the diversity gain — one of the main characteristics describing the spatial abundance of propagating conditions, guaranteeing the reliability of the link. The proposed research presents the derived analytic expression for finite-SNR diversity gain, which helps to define the diversity properties of the MIMO system for a current state: signal-to-noise ratio (SNR), symbol error rate (SER), probability of outage, etc. The obtained solution is verified comparing to the direct numerical definitions' implementation and demonstrated the advantageous computational characteristics.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"118 6 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":"129243197","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}

Device-to-device communication is one such mean that allows devices to experience benefits in terms of shorter communication latency. Currently most device-to-device communication in frequency-division duplex system occurs in uplink spectrum. However, due to unbalanced cellular traffic in uplink and downlink bands may result poor spectrum utilization of network resource. In this paper, we investigate resource allocation where network offers reliable communication using normal cellular and device-to-device communications. We consider flexible allocation for device-to-device communication in both uplink and downlink bands in a frequency-division duplex system. The network optimizes resource allocation to improve the network rate with 99.999 % availability target.

To achieve more flexibility in filter performances, this paper designs nearly perfect reconstruction (NPR) filters by relaxing the Nyquist condition (NYQ), and then, the spectral factorization is employed to extract the final prototype filters. As a result, the proposed prototype filter can outperform the generally used PHYDYAS filter in terms of the frequency selectivity, which leads to better bit-error-rate (BER) result in computer simulations of FBMC.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"6 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":"124960797","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}

Television White Space (TVWS) and Licensed-Assisted Access (LAA) can only utilize the specific frequency band as shared frequency and have no mechanism for sharing the other frequency bands to obtain more frequency resources. We have proposed a dynamic frequency-sharing system with wideband sensing to seek for available frequency band allocated for other wireless systems. In this paper, we propose a framework of the dynamic frequency-sharing in a 5G core network. We focus on the case where component functions of the dynamic frequency-sharing are configured in the base station. We also propose an application scheme of the dynamic frequency-sharing as an LAA extension. Furthermore, we explain a problem and its solution regarding interference with the primary user in the uplink by computer simulation.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"11 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":"122347564","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}
