This paper considers a non-linear energy harvesting (EH) model, better reflecting the properties of practical circuits compared to the linear model, in an amplify-and-forward (AF) relaying network. We focus on the design of relay's power splitting scheme to optimize the system outage performance, and derive the optimal power splitting ratios with both perfect and imperfect channel state information (CSI), respectively. Using the dynamic power splitting scheme, we find that the system outage performance is enhanced in the low signal-to-noise ratio (SNR) regime while converging to an upper bound in the high SNR regime. This finding is significant since it illustrates that the nonlinearity of practical energy harvester brings changes to the design of relaying networks. Simulation results are provided to support our work.

Inspired by random matrix theory, a quantity of eigenvalue based cooperative spectrum sensing methods have been proposed. The results are based on the asymptotical assumptions in need of large numbers of users and samples, which result in inferior performance with a few users. In this paper, sensing methods based on maximum eigenvalue and minimum eigenvalue of LDLT decomposition are proposed respectively with a view to improve the accuracy of decision threshold by means of hard decision criterion. The corresponding expressions of false alarm probability are also derived. Finally, both theoretical analyses and simulations demonstrate that the proposed two methods perform better than the existing eigenvalue based sensing methods for accurate decision threshold.

This paper discusses a statistical property of single- carrier and OFDM signals pulse-shaped by the square- root raised-cosine (RRC) filter. In general, strictly band- limited signals exhibit high peak power, and the baseband signal with large signal dynamic range severely suffers from nonlinearity of power amplifiers. Therefore, in practical systems operated with a pulse-shaping filter, its roll-off factor (or excess bandwidth) should be carefully chosen considering the trade-off between the bandwidth and dynamic range of resulting signals. In this work, we investigate this trade-off relationship for the RRC-filtered single-carrier signals composed of statistically independent input symbols through the analysis of their fourth-order moments. The expression for the complementary cumulative distribution function (CCDF) of the instantaneous power in the case of RRC-filtered Gaussian signals is also developed, which serves as an accurate reference for the RRC-filtered OFDM signals with a large number of subcarriers. Based on these observations, we show that the RRC filtered OFDM signals tend to exhibit larger dynamic range than the conventional OFDM signaling filtered by a periodic sinc function.

Controller Area Network (CAN), the de facto standard in-vehicle network protocol, prompts modern automobile an integrated system that achieves real-time interactions with roads, vehicles and people. Yet such connectivity makes it feasible to illegally access, or even attack the CAN, causing not only privacy disclosure, property damage, but also life threat. In this paper, we analyze intrinsic weakness in CAN protocol that is mostly exploited by attackers and comprehensively survey the existing attacks based on CAN interfaces. Furthermore, we propose an attack evaluation system based on attack tree model and Markov chain to assess the probability of compromising CAN and the steady state of CAN system at the presence of these attacks. Finally, we simulate new steady state when altering the difficulty of a certain attack and the results demonstrate that sometimes improving defense of an attack declines the security level of the entire system instead.

Connecting unmanned aerial vehicles (UAVs) by using cellular networks can significantly expand the civil applications of UAVs, due to much a larger connectivity range and low cost. However, the low-altitude air-to-ground (ATG) channels are different from the traditional terrestrial mobile access channels, and hence need to be characterized specifically. In this paper, a measurement campaign and modeling of the aerial access channels between a UAV and base station (BS) in the typical urban macro-cell (UMa) and rural macro-cell (RMa) scenarios are presented. The channels were sounded at 2.412 GHz and 919 MHz with the horizontal ranges of 420 meters and 10 kilometers, respectively, in the two scenarios. The transmitter equipped with two omnidirectional antennas was fixed on a fourrotor UAV which flew horizontally at various altitudes from 25 to 150 meters. The receiver was installed on the top of five-storey buildings to emulate a BS. The path loss (PL) was measured and the statistical models have been proposed which are based on the corresponding 3GPP territorial channel models but adjusted by adding correction factors (CFs). The CF is relevant to the UAV height in the UMa scenario. For the RMa scenario there is a breaking point with respect to the horizontal distance and hence a segmented function for the CF is proposed. The new PL models can help to establish the ATG channel models and support the design of air-borne access technologies for the LTE networks.

An analytical model is developed to evaluate the network performance of an IEEE 802.11ac Wireless Local Area Network (WLAN) in support of delay sensitive video services over multiple channels. Specifically, the channel bonding probability and the channel access delay of wireless users are analyzed, considering the contentions among legacy and ac users in the same channel and across multiple channels. Based on the analysis, the network capacity region, i.e., the maximum number of traffic flows can be supported with the bounded delay performance in a multi-channel WLAN with and without channel bonding, is then derived. Our analysis shows that channel bonding can greatly improve the network capacity when the channel is under-utilized with a small number of legacy users co-existing with the ac users; yet channel bonding is not always favorable and it may degrade the network capacity when the number of legacy users increases due to the increased contentions in the network. The analysis provides important guidance for effective admission control and channel bonding strategies to guarantee the bonded service delay of realtime applications. Extensive simulations validate the analysis.

Millimeter wave (mm-wave) communication is essential for the next generation cellular networks. To exploit mm-wave frequencies, directional transmissions have to be applied to compensate the high propagation loss. Due to directional transmissions, initial access procedure of mm-wave communication systems needs specific design compared to conventional networks operating at sub-6 GHz. This paper focuses on an important step in the initial access procedure, namely broadcast signaling design for cell discovery. An analysis of such design is conducted based on an information theoretical approach, where four fundamental beam patterns, which cover most of the design options, are compared. Their performances in terms of cell discovery latency and signaling overhead are analyzed. The analysis reveals three key findings: (i) the average cell discovery latency depends only on beam duration and frame length, if the entire beacon interval can be accommodated in one frame; (ii) for low latency, single beam exhaustive scanning provides the best performance, but results in high signaling overhead; (iii) simultaneous multi-beam scanning can significantly reduce the overhead, and provide the flexibility to achieve trade-off between latency and overhead. The analytical results are verified by extensive simulations.

We consider efficient communications over the multiple-input multiple-output (MIMO) multiway distributed relay channel (MDRC) with full data exchange, where each user, equipped with multiple antennas, broadcasts its message to all the other users via the help of a number of distributive relays. We propose a physical-layer network coding (PNC) based scheme involving linear precoding for channel alignment, nested lattice coding for PNC, and lattice-based precoding for interference mitigation. We show that distributed relaying achieves the same sum-rate as cooperative relaying in the high SNR regime in most scenarios, which implies that the proposed scheme with distributed relays is more suitable for practical systems than the schemes with cooperative relays.

Software Defined Vehicular Networks (SDVN) brings a set of attractive features to vehicular networks along with an upgrade in the performance. Yet, SDVN suffers from frequently compelling to contact the centralized control plane, which in turn generates a high latency and packet overhead in the communication. The current solution to reduce the delay, proactive approach, does not bring the packet overhead down and impose a lot of stress on the controller with a decline of Packet Delivery Ratio (PDR). As an alternative, we introduce a source routing based flow instantiation operation with intelligent route caching that reduces the extent of communication with the control plane, but still manages to utilize the knowledge of controller while maintaining a lower latency and packet overhead.

This paper addresses the optimal charging scheduling problem for Electric Vehicles (EVs) in an intelligent workplace parking lot powered by both the Photovoltaic Power (PV) System and the Power Grid. Due to the uncertain charging requirements of different EVs and time-varying available renewable energy, the charging load from the parking lot may bring a new challenge to the Power Grid. By minimizing total cost of the parking lot, we design a dynamic charging scheduling scheme to manage the charging processes of EVs based on the real- time information of EVs and renewable energy from the PV system. Numerical simulations are carried out to demonstrate the efficiency of the designed charging scheduling scheme.
