Generalized Frequency Division Multiplexing (GFDM) is a recently proposed multicarrier waveform which is being considered as one of the possible candidates for 5G wireless access technology. Key advantages of GFDM are flexibility and low spectral side-lobes which render it the ability of carrier aggregation and reduced adjacent channel interference. However due to its non-orthogonal nature GFDM suffers from the problem of self-inter-carrier interference (self-ICI) which occurs between time-slots of adjacent subcarriers in the signal. Due to self-ICI, the bit-error rate (BER) performance of GFDM is severely affected under low SNR regime. Moreover application of MIMO technique to GFDM further adversely affects the BER due to inter-antenna interference (IAI) between the transmit antennas. To mitigate this problem, spatial modulation has been applied to GFDM and its BER performance with respect to V-BLAST based GFDM is studied under flat Rayleigh fading channel condition through computer simulations.

The evolution of wireless communications requires the development of long-life or sustainable power sources. One method currently receiving increasing attention in current literature, compared to other energy solutions, is the application of Radio-frequency (RF) energy as an alternative energy source for low-power devices. The presence of various wireless services makes a challenge to this technology with respect to the design of multiband antennas. A 3-D multi-band antenna with adaptive form is designed purpose of integration in available circuits without changing their form and characteristics and also to scale down the antenna size. The current study presents a novel efficient antenna for the reception of ambient RF energy from cellular network frequency bands and Wi-Fi sources simultaneously. The antenna operates in five bands of frequency including GSM 1800MHz, UMTS 2100MHz, WLAN 2.4GHz, WLAN 5.2GHz and WLAN 5.8GHz. The volume of antenna is small, 55mm×25mm×15mm. The simulation and measurement results of the proposed design are consistent with an omnidirectional pattern, a satisfying gain around 2dBi and high efficiency over 96%.

The label tree-based classification is one of the most popular approaches for reducing the testing complexity to sublinear with the large number of classes. One of the popular approaches to generate the label tree is to apply recursively a spectral clustering algorithm to an affinity matrix for partition set of class labels into subsets, each subset corresponds to a child node of the tree. To obtain the affinity matrix from confusion matrix, a set of N binary one-versus-all classifiers is trained and applied on validation set, where N is number of classes. However, these approaches are not reliable when there are a large number of classes because it is too costly to train these classifiers. Furthermore, the affinity matrix could not reflect the real similarity among classes due to the classification accuracy can be low. In addition, the resulting label tree may not be balanced due to the objective function of spectral clustering penalizes unbalanced partitions. In this paper, to achieve better similarity measurement between classes and without using one-versus-all classifiers, we adopt the sum match kernel to get similarity matrix. Moreover, we propose a heuristic for learning balanced tree structure by adjusting the number of class labels in clusters after the spectral clustering is done. The experimental results on benchmark datasets SUN-397 and Caltech-256 show that the performance of the proposed approach outperforms significantly the other approaches.

Recently, high-precision indoor positioning has become an important technology in the O2O (online-to-offline) services. In indoor positioning method, fingerprinting is better than trilateration in that it is possible to avoid problems that are not effectively applied to indoor wireless attenuation model. Fingerprinting compares the radio propagation condition that is measured at the time of positioning with the set of radio propagation conditions that are measured in initial training, and estimates the position according to its similarity. However, since radio waves are superimposed by the reflection of the walls and floors in the indoor environment, positioning accuracy decreases when the layout of the environment is changed after creation of the initial training data. To solve this problem, we propose a method to infer whether some obstacle exists between each pair of transmitter and receiver by principal component analysis of RSSI (Received Signal Strength Indicator) of multi-frequency, to detect LOS (Line-of-Sight)-shielded transmitters and to eliminate them from calculation for positioning. Comparing with existing method on typical fingerprinting, our method improved up to 31% on robustness.

The power quality of grid-connected inverters depends much on voltage parameters estimated by phase-locked loops. This paper proposes a robust technique for fast and accurate estimation of fundamental parameters of single-phase grid voltage under harmonics. The proposed technique bases on the least squares method using Levenberg-Marquardt algorithm to estimate the parameters of grid voltage. This does not base on interdependent loops offering stability and easy estimating process. It can also reject the negative effects caused by the presence of the dc offset as well as the harmonics. The simulation results in MATLAB/Simulink validated the robustness and accuracy of the proposed technique compared to the phase locked-loop basing on a second-order generalized integrator (QSG-SOGI).

Time series forecasting is paid a considerable attention of the researchers. At present, in the field of machine learning, there are a lot of studies using an ensemble of artificial neural networks to construct the model for time series forecasting in general, and consumer price index (CPI) forecasting, in particular. However, determining the number of members of an ensemble is still debatable. This paper proposes the way of constructing a model for CPI forecasting and designing a multi-objective evolutionary algorithm in training neural networks ensembles in order to increase the diversity of the population. Two objectives of the training problem include: Mean Sum of Squared Errors and diversity. We experimented the model on three data sets and compared methods. The experimental results showed that the proposed model produced better in investigated cases.

In this paper, we propose a direct sampling receiver which can exploit multipath characteristic of flat fading channels to improve Bit Error Rate (BER) performance of Differential Chaos-Shift Keying (DCSK) systems. Structure of the proposed receiver consists of a conventional correlator-type receiver and an oversampling block at the input. This oversampling helps the receiver to specifically determine the delayed-signal components from the channel, which can be combined together in order to increase the ratio of signal-to-noise (SNR) at the output. Discrete-time models for the conventional transmitter, flat Rayleigh fading channel with delay paths as well as the proposed receiver are built and described in detail. Dependence of BER performance on typical parameters of the system, i.e., ratio of Eb/N0, number of delay paths, spreading factor, number of samples per chip, fading coefficients, and path delays, are determined by means of numerical simulations. Interestingly, obtained results point out that the system performance is significantly improved when the number of delay paths increases.

A novel technique is proposed to greatly enhance the convergence property of stationary iterative solvers applied for the solution of scattering from two-dimensional random rough surfaces. The proposed method extends the standard improvement step to enable the use of multiple correction vectors, leading to a significantly improved convergence rate of stationary iterative methods with negligible increases in computational complexity. Spectral acceleration technique is also applied to reduce a computational burden and storage requirements. Numerical results are shown to demonstrate the advantages of the proposed technique.

In this paper, we propose a Spatial Modulation (SM) with full diversity for 4 transmit antennas, called DS-SM, by designing SC codewords and incorporating them with a Diagonal Space Time Block Code. Similar to the conventional SM scheme, the proposed scheme only activates an antenna element at a time for signal transmission. However, it is different from the conventional SM in that it is able to achieve full diversity. In order to attain low detection complexity, an ML detector based on sphere decoding is presented. Computer simulation shows that the proposed DS-SM scheme outperforms some existing STBC-SM techniques in terms of both bit error rate (BER) performance and effective throughput.
