In this paper, we consider a downlink multi-channel wireless virtualized network consisting of a physical base station (PBS) and multiple mobile user equipments (MUEs) with energy harvesting capability. The PBS is owned by an infrastructure provider (InP) and is virtualized into a set of virtual BSs (VBSs). Each VBS is owned by a virtual network operator (VNO) and serves a set of MUEs by using the allocated channels. Specifically, each MUE can use all the channels allocated to the serving VBS and different MUEs share the channels by using TDMA. In addition, each MUE can harvest energy and decode information from the signals transmitted from the VBS, i.e., each MUE is allocated with a fraction of time for information decoding and harvests energy in the rest time fractions. Under the above setup, we investigate the problem to maximize the sum rate of the MUEs by optimizing the channel allocation, the power allocation and the time allocation, under the maximum transmit power constraint and the minimum harvested energy constraint. The problem is nonconvex and we propose an efficient iterative algorithm based on alternating direction optimization method (ADOM) to address it. It is shown that the proposed algorithm converges fast and outperforms the reference algorithms without wireless network virtualization.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127663351","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}

To improve the performance, the detector usually adopts a self-iteration which iteratively estimate the soft bit information (SBI). This paper proposes two main idea to improve the performance as well as to reduce the complexity of the PIC-MMSE based MIMO detector. In order to reduce the complexity, we map PIC-MMSE filtered symbol to a specific region so that the detector does not require any search process to find the minima. In addition, we propose an optimization technique to increase the reliability of the soft symbols. Simulation results show that the complexity of the proposed method is reduced to linear-order without performance degradation, and the proposed optimization method can efficiently improve the performance with reasonable complexity.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128148379","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}

However, with its current architecture, VANET has not been able to fulfill some of the necessities of vehicular networks and most importantly still lacking flexibility and programmability. Recently Software Defined Networking (SDN) has been introduced into the vehicular domain in order to overcome the shortcomings in VANET. Though the introduced Software Defined Vehicular Network (SDVN) architectures provide flexibility and programmability into the networks with higher packet delivery ratios (PDRs), they have violated the stringent delay requirement in VANET, provoking questions on its usability. So in this paper, we propose a novel SDVN architecture which gives priority to delay requirements in VANET. We have also compared the delay profiles of VANET and other SDVN architectures with our proposed architecture, both theoretically and experimentally.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128152915","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}

Improved constellations are obtained through solving optimization problems aiming at minimizing the system symbol error rate (SER), subject to lighting constraints. A new system mathematical model is formulated with the SDSN taken into account. By maximizing the minimum Euclidean distance (MED) between the symbols, improved constellations are discovered with different lighting constraints. Furthermore, our multi-carrier design embraces the DC-informative framework, i.e. the DC bias carries information jointly with the subcarriers to provide high power efficiency. With equal spectrum efficiency, the power gain of our DC-Informative optical (DCIO) OFDM over the conventional phase shift keying base OFDM scheme ranges from 3–30dB with parameters of practical interest.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128329113","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 BS is equipped with large-scale antenna arrays, while each user is equipped with two antennas (one for transmitting and the other one for receiving). The linear signal processing technique based on the maximum-ratio combining/maximum-ratio transmission (MRC/MRT) is adopted at the BS. The asymptotic expressions of signal-to-interference-plus-noise ratio (SINR) of uplink and downlink are derived respectively when the number of antennas of the BS tends to infinity. Through the theoretical derivation, it is shown that the detrimental impact of the loop interference (LI) can be eliminated by the very large number of antennas at the BS if the power scaling scheme is appropriately applied, as well as the effect of multi-user interference (MUI) and inter-user interference (IUI). Moreover, the Monte Carlo simulations show that the spectral efficiency of the multi-user full-duplex massive MIMO system is better than the half-duplex (HD) counterpart when the number of receive/transmit antennas at the BS is large.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133420621","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}

Unlike most of the existing works, both the transmit and circuit energy consumptions are considered and especially the circuit energy consumption is modeled as a function of the data rate, rather than as a constant. In order to simplify its solution, the optimal energy-efficiency problem is transformed into a two-stage problem, stage 1: optimal power allocation of terminals; and stage 2: distributed relay assignment. Summarizing the results achieved at stages 1 and 2, a distributed relay assignment and power control technique is proposed for optimal energy-efficiency.

In particular, the phase-adjustment-only limitation of a phase array and limited RF chains render the conventional design of purely digital beam-former inapplicable for the hybrid beamforming architecture. To address this issue, a novel design of hybrid beamformer, comprising a digital and an analog (phase-array) components, is presented for hybrid interference cancellation, which is tailored for the mmWave channel characteristics and overcomes the hardware constraint of massive MIMO. The systematic design approach builds on the recently developed method of decomposing the analog beamformer into Kronecker products of unit-modulus component vectors which are designed to cancel interference arriving from different directions. Then a follow-up low-dimension digital beamformer is designed to further enhance the signal quality for a given number of RF chains. It is shown that the proposed hybrid beamformer attains similar performance as the fully digital minimum-mean-square-error (MMSE) beamformer in the interference-limited regime.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130525720","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}

However, as OFDM suffers from high peak-to-average power ratio (PAPR), the blanker may falsely treat the high amplitude signal as impulsive noise. Therefore, PAPR reduction methods have been employed to improve the performance of the blanker. However, most PAPR reduction methods have some disadvantages. This paper proposes to use precoding to reduce the PAPR of the OFDM system and to improve the performance of the blanker at the same time.
