Optimal Codeword Design for Precoded UWB (PUWB) Systems
Abstract— A precoding technique applied to symbols transmitted in an ultra-wideband (UWB) system was proposed in [1], which can concentrate the signal power at the receiver to fa...

Low noise amplifier design for ultra-wideband radio
A new theoretical approach for designing a low-noise amplifier (LNA) for the ultra-wideband (UWB) radio is presented. Unlike narrowband systems, the use of the noise figure (NF) p...
