New configuration of multiband / broadband Planar inverted FAntenna (PIFA) is investigated. The antenna is a V-shaped patch with unequal arms coupled electromagnetically to single feed triangular PIFA thorough two unequal slots' dimensions. The six multiband operations are achieved due to the different lengths and widths of the V-shaped patch as well as the two coupling slots. Two more modes ca...

This paper presents a subband approach to financial time series prediction. Multivariate empirical mode decomposition MEMD is employed here for multiband representation of multichannel financial time series together. Autoregressivemoving average ARMA model is used in prediction of individual subband of any time series data. Then all the predicted subband signals are summed up to obtain the over...

Cognitive radios are being proposed for recovering unused spectrum holes in time and space. Unfortunately the metric of detection-sensitivity while being useful for algorithm designers is not indicative of a system’s ability to recover spectrum holes (especially spectrum holes in space). In this paper we extend the safety and performance metrics of Fear of Harmful Interference (FHI ) and Probab...

A modified Saleh-Valenzuela channel model has been adapted for Ultra Wideband (UWB) system. The suggested realistic channel is assessed by its distribution of fading amplitude and time of arrivals. Furthermore, the propagation characteristic has been distinct into four channel models, namely CM 1 to 4. Each are differentiate in terms of cluster arrival rates, rays arrival rate within each clust...

In this paper, the amplitude and frequency AM–FM modulation model and a multiband demodulation analysis scheme are applied to formant frequency and bandwidth tracking of speech signals. Filtering by a bank of Gabor bandpass filters is performed to isolate each speech resonance in the signal. Next, the amplitude envelope AM and instantaneous frequency FM are estimated for each band using the ene...

We study multiband semiconducting nanowires proximity-coupled with an s-wave superconductor. We show that, when an odd number of subbands are occupied, the system realizes a nontrivial topological state supporting Majorana modes. We study the topological quantum phase transition in this system and calculate the phase diagram as a function of the chemical potential and magnetic field. Our key fi...

Multi-Coset (MC) sampling is a well established, practically feasible scheme for sampling multiband analog signals below the Nyquist rate. MC sampling has gained renewed interest in the Compressive Sensing (CS) community, due partly to the fact that in the frequency domain, MC sampling bears a strong resemblance to other sub-Nyquist CS acquisition protocols. In this paper, we consider MC sampli...

We present a method for binary segmentation of multiband images based on a combination of dimensionality reduction techniques (Weighted PCA and Quadratic Programming Feature Selection), classification methods (Gaussian Mixtures Models and Random Forest) and segmentation method (Quadratic Markov Measure Field Models). In this work, four pixels descriptors are presented: Color, Discrete Cosine Tr...

This paper presents the design of elliptical slot antenna for multiband applications. The suggested antenna covers L-band, WIMAX, WLAN and X band. By placing inverted T-shaped stub and three reverse U-shape stubs, the resonating characteristics of the antenna are observed. The resonating frequencies are 1.95, 4.14, 5.05, 5.89 and 9.15 GHz respectively. The designed antenna shows good return los...
