The extremely high sampling rate is a challenge for ultra-wideband (UWB) communication. In this paper, we study the compressed sensing (CS) based impulse radio UWB (IR-UWB) signal detection and propose an IR-UWB signal detection algorithm based on compressive sampling matching pursuit (CoSaMP). The proposed algorithm relies on the fact that UWB received signal is sparse in the time domain. The ...

The central challenge of ultra-wideband (UWB) radio is to overcome its intrinsic complexity. This paper argues for the use of high-speed sampling and a front-end FFT as the paradigm of choice for robust performance and low energy consumption in certain ultra-wideband designs. Assuming the need to approach optimal performance, it highlights the complexity advantage of frequency domain (FD) over ...

The emergence of commercial wireless devices based on ultra-wideband radio technology (UWB-RT) is widely awaited and anticipated. UWB-RT is not only applicable to communications, imaging and ranging, it also promises to alleviate the problem of increasingly scarce spectrum resources while enabling new wireless applications and business opportunities. These prospects have caught the early attent...

This work quantifies and analyzes tremor using Ultra Wide Band (UWB) radio technology. The UWB technology provides a new technology for non contact tremor assessment with extremely low radiation and penetration through walls. Tremor is the target symptom in the treatment of many neurological disorders such as Parkinson’s disease (PD), midbrain tremor, essential tremor (ET) and epilepsy. The com...

Ultra-wideband (UWB) technology has become one of the most promising technology for shortrange high speed data communication due to its high data transmission rate and large bandwidth. These systems utilize the frequency band from 3.1GHz to 10.6 GHz, which is al‐ located to the UWB systems by the Federal Communications Commission (FCC) [1]. In this ultra-wide spectrum, several unlicensed short ...

This paper presents an ultra-wideband (UWB) low noise amplifier (LNA) using two stage cascading topology to obtain high gain. Inductive degeneration and peaking inductor techniques are used to obtain wideband matching and flatness of gain. The proposed UWB LNA is implemented by using 180nm based CMOS TSMC technology using Advanced Design System (ADS) software.LNA achieves maximum gain of 15.5dB...

Fourier analyzer concept that generalize the waveform communications to include chaotic carriers can be used to discuss and optimize detection problems. Using this new description it is possible to develop new detector configurations with improved performance for chaotic communications that may be used in ultra-wideband radio (UWB). Radio communications via channels already occupied by traditio...

After the Federal Communication Commission (FCC)’s authorization of frequency band of 3.1 to 10.6 GHz for unlicensed radio applications, ultra-wideband (UWB) technology be‐ come the most promising candidate for a wide range of applications that will provide signif‐ icant benefits for public safety, business and consumers, and attracted a lot attention both in industry and academia. The antennas...

Ultra wideband (UWB) radio communication is capable of a high data rate with low radiated power. A key issue for UWB design is LNA input/output matching over a wide bandwidth: 3 to 5GHz for the lower band and 3 to 10GHz for the entire band. Several UWB LNAs have been proposed in recent years. The UWB CMOS LNA presented in [1] employs a Chebyshev filter for input matching and a source follower f...

Ultra wideband radio (UWB) is a new wireless technology that uses narrow pulses to transmit information. Implementing an “all-digital” UWB receiver has numerous potential benefits ranging from low-cost and ease-of-design to flexibility. Digitizing an RF signal near the antenna, however, introduces its own set of challenges and has traditionally been considered infeasible. A high-speed, high-res...
