Abstract—This paper presents the refinement method for two beams formation of wideband smart antenna. The refinement method for weighting coefficients is based on Fully Spatial Signal Processing by taking Inverse Discrete Fourier Transform (IDFT), and its simulation results are presented using MATLAB. The radiation pattern is created by multiplying the incoming signal with real weights and then...

The realization of Software Defined Radio (SDR) requires flexible RF front-end to accommodate multiple standards in different frequency bands. In this review paper, we survey the literature over the period 1995–2011 and discuss the state-of-the-art multiband and wideband LNAs in context of different receiver architectures suitable for SDR. Wideband and multiband LNA designs reported in open lit...

Wideband communications permit the transmission of an extended frequency range compared to the traditional narrowband. While benefits for automatic speaker recognition can be expected, the extent of the contribution of the additional bandwidth in wideband is still unclear. This work compares the i-vector speaker verification performances employing speech signals of 0-4 kHz, 4-8 kHz, and 0-8 kHz...

OF THE DISSERTATION xv CHAPTER 1. Ultra-wideband Communication Overview 1 1.

Recent advances in wideband impulse technology, low power communication along with unlicensed band have enabled ultra wide band (UWB) as a leading technology for future wireless applications. This paper outlines the applications of emerging UWB technology in a private and commercial sector. We further talk about UWB technology for a wireless body area network (WBAN).
