Application of time-reversal-based processing techniques to enhance detection of GPR targets
Vinicius R. N. Santos, Fernando L. Teixeira
In this paper we analyze the performance of time-reversal (TR) techniques in conjunction with various Ground Penetrating Radar (GPR) pre-processing methods aimed at improving detec…
Space-Time Block Diagonalization for Frequency-Selective MIMO Broadcast Channels
Carlos A. Viteri-Mera, Fernando L. Teixeira
The most relevant linear precoding method for frequency-flat MIMO broadcast channels is block diagonalization (BD) which, under certain conditions, attains the same nonlinear dirty…
Interface-Flattening Transform for EM Field Modeling in Tilted, Cylindrically-Stratified Geophysical Media
Kamalesh Sainath, Fernando L. Teixeira
We propose and investigate an "interface-flattening" transformation, hinging upon Transformation Optics (T.O.) techniques, to facilitate the rigorous analysis of electromagnetic (E…
