Design and Hardware Implementation of a Reconfigurable Mostly Digital IR-UWB Radio

A proposal for reconfigurable IR-UWB implemented in field-programmable gate array (FPGA) as proof of concept for reconfigurable data rates, spectra, and ranges, which satisfy the need for a wide range of applications

A. Lecointre et al., 2010 [86]

A Largely Reconfigurable Impulse Radio UWB Transceiver

A proposal of an efficient digital baseband architecture for reconfigurable IR-UWB transceiver. The capacity for reconfiguration includes data rates, chip duration, pulse duration, processing gain, and occupied bandwidth. The other proposed FPGA programming method validates this architecture proposal.

Low Power Amplitude and Spectrum Tunable IR-UWB transmitter

A low power with reduced complexity carrierless transmitter with the ability to tune the spectrum. The buffer can be turned off between pulse intervals to reduce power consumption. The authors present the implementation of the transmitter circuit with three main parts: the pulse generator, output buffer, and power control circuit.

Reconfigurable, Spectrally Efficient, High Data Rate IR-UWB Transmitter Design Using a Δ − Σ PLL Driven ILO and a 7-Tap FIR Filter

A prototype proposal for far infrared (FIR) pulse-based UWB transmitter implemented in a 90 nm complementary metal-oxide-semiconductor. The transmitter is a digitally reconfigurable 7-tap FIR pulse generation which uses Δ − Σ phase-locked loop (PLL) for efficient frequency control and 16-phase injection-locked oscillator.

A Low Power, Reconfigurable IR-UWB System

A proposal for a complete UWB transceiver system which is fully reconfigurable in terms of bandwidth, data rate, processing gain, and ranging accuracy. The proposal validation is achieved as Integrated Circuit implementation to demonstrate power/flexibility trade-off in an integrated solution.
