To improve the reliability of telephone-based speaker verification systems, channel compensation is indispensable. However, it is also important to ensure that the channel compensation algorithms in these systems surpress channel variations and enhance interspeaker distinction. This paper addresses this problem by a blind feature-based transformation approach in which the transformation paramet...

In this paper, we proposed a novel efficient method of analyzing the ergodic channel capacity of the cooperative amplify-and-forward (CAF) relay system. This is accomplished by employing a very tight approximate moment generating function (MGF) of end-to-end signal-to-noise ratio of 2-hop multi-relay system, which is In this paper, we proposed a novel efficient method of analyzing the ergodic c...

Image compositing combines visual elements from multiple images aiming to produce natural-looking results. Poisson-imageediting methods can generate seamless compositions, but introduces color changes in the inserted elements, which often generate unrealistic and unpleasing results. Recently, Henz et al. have presented an approach for controlling the amount of color changes in the inserted imag...

Bose-Einstein condensation (BEC) in two dimensions (2D) (e.g., to describe the quasi-2D cuprates) is suggested as the possible mechanism widely believed to underlie superconductivity in general. A crucial role is played by nonzero center-of-mass momentum Cooper pairs (CPs) usually neglected in BCS theory. Also vital is the unique linear dispersion relation appropriate to weakly-coupled “bosonic...

Abstract Galileo E1 Open Service (OS) signal is transmitted with the modulation of Composite Binary Offset Carrier (CBOC). CBOC has a main drawback that is the autocorrelation function has multiple sidepeaks, which will lead to ambiguous acquisition. The high rate of data bit and secondary code makes it very difficult to increase coherent integration time. This paper will propose a new scheme b...

We present a new vectorial total variation (VTV) method that addresses the problem of color consistent image filtering. Our approach combines insights based on the double-opponent cell representation in the visual cortex with state-of-the-art variational modelling using VTV regularization. Existing methods of vectorial total variation regularizers have insufficient (even no) coupling between th...

In this paper the impact of a Radio over Fibre (RoF) subsystem on the capacity performance of Wideband Code Division Multiple Access (WCDMA) is evaluated. The study investigates the use of pilot aided channel estimation to compensate for the optical subsystem nonlinearities for different channel conditions, estimation intervals, and coding schemes. The results show that pilot aided channel esti...

This paper focuses on the design of a multiuser receiver structure for the reverse link of a code-division multiple-access communication system, in the presence of multipath effects and using an antenna array at the base station receiver. The algorithm presented in this paper solves the complex multidimensional problem of channel estimation in this complex scenario using a maximum-likelihood ap...

We present a microfluidic-based method allowing for the controlled production of lipid particles with encapsulated magnetic nanoparticles (MNPs). Within the same device, the magnetic properties of the composite particles are tested as they flow downstream. The effect of the fluid properties and flow parameters on the size of the microparticles containing MNPs is studied using standard flow visu...

A detailed theoretical study of composite plasmonic waveguide structures is reported. Expressions for modal expansion coefficients, optical transmittance and surface intensity are presented and used to describe the behavior of dielectric channel waveguides containing a short gold-coated section. The superstrate refractive index is shown to control modal beating and modal attenuation in the gold...
