In this paper, feed-forward pre-equalization in conjunction with a PAM modulation scheme are proposed for use in wireless visible light communication (VLC) systems in order to enable the transmission of data rates >1 Gb/s. Simulation results demonstrate that simple few-tap feed-forward pre-equalization is able to remove the intersymbol interference caused by the limited link bandwidth of a line...
In Ultra-Wideband (UWB) microwave imaging for breast cancer detection, UWB pulses illuminate the breast and the echoes are processed to create images. Adoption in screening campaigns requires the development of a fully-engineered medical imaging tool. In this paper we report on our experience with the design of this kind of UWB imaging system and illustrate some of the challenges the designers have...
We present a novel detection system for nuclear magnetic resonance (NMR) logging tool with direct connection of receiver to low inductance antenna. The detection system contains receiver and signal acquisition circuit with high signal-to-noise ratio (SNR). The direct balanced connection of receiver to antenna increases SNR of the NMR signal. The first stage of receiver has a balanced input built on...
