Traffic prediction is of paramount importance for the correct management of network infrastructures. Most research efforts try to forecast the aggregated traffic over the network and over large time windows. In this work, we tackle the problem the other way around. That is, we predict the behaviour of individual users over short time windows. First, we investigate the contribution of the most data eager users to the global network traffic. We do it by analyzing network traces coming from several thousand real users. Then, we design a technique, based on a combination of Natural Language Processing (NLP) and Long Short-Term Memory (LSTM) machine learning models, that leverages past navigation patterns to predict sudden changes in the amount of resources consumed by each user. Finally, we evaluate our method using real data finding it is able to predict about 80% of the users that will rump up their network needs in most realistic scenarios.

Non-orthogonal spectrally efficient frequency division multiplexing (SEFDM) saves bandwidth by compressing the frequency spacing between the subcarriers. This is at the cost of introducing inter-carrier interference (ICI) between the subcarriers. This self-created ICI compounded by the signal degradation caused during wireless propagation in multipath environments, complicates the task of channel estimation and equalisation. Recent studies suggest that combining zero padding (ZP) with SEFDM signals can simplify the challenge of channel estimation and equalisation in the frequency-domain. In this work, we validate experimentally the new ZP scheme through over-the-air transmission of radio frequency (RF) signals. Experimental results prove that using ZP in SEFDM enhances the channel estimation and equalisation accuracy, in comparison to conventional cyclic prefix (CP)-SEFDM. In addition, it is shown that ZP-SEFDM offers robustness against timing offsets.

In the near future, unmanned aerial vehicles (UAVs) will have enormous potential applications for next generation wireless communication systems, in which they can collaborate to serve several user equipment (UE) for communication purposes.Disaster scenarios are a relevant research topic, in which UAVs can aid establishing connections in circumstances where base stations (BS) may be inoperative.The resulting UAV positioning affects the overall spectral efficiency (SE) in each UAV-UE link. Moreover, UEs energy consumption must be optimized since the finite amount of energy available is one of the most significant limitations of these devices. Therefore, it is essential to determine the lowest power consumption necessary to guarantee a minimum SE throughput in a disaster location.In this paper, we investigate a cooperative meta-heuristic (MH) optimization algorithm for both the UAVs and UEs. We propose two parallel optimization approaches: one is the UAV search position process to find the best possible location to serve its pre-allocated UEs; the other is finding the lowest possible uplink (UL) power values for each user’s equipment. The preliminary results show that the Differential Evolution (DE) algorithm reaches good quality solutions in acceptable computation runtime.

A long-period fiber grating (LPFG) structure based on D-shaped fiber is proposed, where a graphene oxide (GO) film layer is deposited on the fiber by the dipping method to jointly construct a new humidity sensor. The D-shaped fiber structure can provide a stronger evanescent field than conventional fibers, and therefore offer much higher sensitivity. The maximum average sensitivity achieved by the sensor in the range of ambient humidity of 20-80% RH (relative humidity) is -0.1908 nm/% RH, and the linearity is 0.998. The experimental results show that the humidity sensor has higher response sensitivity, and improved linear response characteristics. It provides a beneficial exploration for the development of low-cost, easy-to-manufacture, and highly sensitive fiber-optic humidity sensors.

The combination of power line communications (PLC) and radio frequency (RF) is essential for implementing new applications in smart grid and vehicular communications. In this paper, we propose a non-orthogonal multiple access (NOMA) based dual-hop hybrid wireless-power line communication (PLC) system with a decode-and-forward relay. The wireless channel is characterized by Nakagami-m fading under an additive white Gaussian noise, while the PLC channel is characterized by a Log-normal distribution with Bernoulli Gaussian noise including both background and impulsive noise components. New closedform expressions for the outage probability, and the asymptotic outage probability are derived under the practical assumption of imperfect successive interference cancellation (SIC) and verified via extensive representative simulations. For more insights on the outage performance, we also analyze the diversity order. Additionally, we proposed a power allocation optimization technique to achieve outage-optimal performance. The results show that the system outage probability improves as the arrival probability of the PLC impulsive component decreases. Finally, to highlight the achievable performance gain, the performance of the proposed system is compared against a benchmark OMA-based system.

A novel access-metro network architecture based on lightpath flows, using coherent transmissions, supporting numerous passive optical networks (PONs), and integrating multiple services, including 4G/5G/6G mobile networks, is presented. The lightpaths flows are flexibly assigned in an ultra-dense wavelength division multiplexing PON (UDWDM-PON) with dynamic bandwidth allocation. The mobile networks are integrated in a cloud radio access network (C-RAN), which provides reconfigurable capabilities between the remote radio heads (RRHs) near the users’ premises and the baseband units (BBUs) located at a centralized central office (CO) in the metro side. The whole access-metro proposal incorporates the PONs, including the C-RAN services, in a versatile coherent dual optical network (VERSONET) ring architecture; enabling resilience, real-time centralized control, provisioning and also administration and maintenance (OAM) functions.

The multiple-input multiple-output (MIMO) systems provide high data rates and spectral efficiency performance. However, the fundamental problems with these technologies are their rising computational complexity and power consumption. The aim of this paper is to minimize the total transmit power of the MIMO system subject to the target bit rate of the user. The procedure of assigning different transmit power values to transmiting antennas and selecting the optimum total transmit power with respect to the user’s bit rate constraint is computationally hard, especially when the size of the possible transmit power scenarios arises exponentially. To this end, an efficient quantum strategy called Constrained Quantum optimization Algorithm (CQOA) is proposed in this work, which searches faster (exponentially) for the optimum result. The proposed quantum strategy is compared with the various optimization algorithms such as Genetic Algorithm (GA). Simulation results highlight the fact that the CQOA outperforms the GA in terms of computational complexity.

With the aging of the population in various countries, the impact of Alzheimer’s disease on humans is becoming more and more obvious. It is very necessary to propose an Alzheimer’s detection system. This paper attempts to use the singular spectrum analysis trend extraction method to complete the task of Alzheimer’s detection with speech. First, the singular spectrum analysis is performed on the speech signal, and the components obtained by the singular spectrum analysis are divided into a trend part and a detrend part according to the energy ratio. Second, feature extraction is performed on the trend part and the detrend part of the speech signal respectively. These features include multidimensional voice program, the gammatone frequency cepstral coefficient, and the Power-normalized cepstral coefficients. Then, use random forest to calculate the importance of feature vectors, and select the top 30 features that random forest considers the most important as the features used in this article. Finally, random forest is used for classification.
