“…Frequency hopping among the different carriers does not change the average transmit power (7), but it does reduce the PSD (5) and (6). When the frequency hooping is applied it is possible to keep the PSD at the initial level by increasing the pulse amplitude A.…”

The present paper describes the physical layer of an Ultra-Wideband Impulse Radio (UWB-IR) communication system, together with its implementation in a fully integrated transceiver. The objective of this work was to design and test a low-power radio communication system for medium data-rate, short-range communication. The system is based on Frequency Hopping On-Off Keying modulation (FH-OOK) for transmission, combined with a non-coherent demodulation scheme in the receiver. A fast-phase synchronization method for the receiver was also developed. A single chip transmitter/receiver integrated circuit (IC), incorporating the radio frequency system and the base-band signal processing chain, was produced using a 0.13 µm CMOS process. Test results showed the maximum data rate for the radio interface to be 20 Mb/s, and a reliable link was obtained at a distance of 5 m, without recourse to error-correction convolutional codes. Maximum power consumption was less than 20 mW. The simple hardware architecture, low power consumption and high achievable data rate make this system suitable for small, portable battery-powered devices.This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE "GLOBECOM" 2009 proceedings.

This paper presents a calculation method to analyze ultra-wide band pulse shapes used for wireless communication using the IEEE 802.15.4a standard. The presented equations provide a simple way for designing a standard compliant pulse shape generated with low power consuming circuitry. The main conclusion is that an average power measurement will obtain the same value for all presented pulse shape variations.

“…The basic idea of most published IR-UWB PGs is to use a high-frequency waveform generator (HFWG), which can be an oscillator, phase-locked loop or delay-line (DL) etc., and shape the output signal to generate the desired envelope by mainly three approaches: filtering [4], spectrum mixing [5,6] or multi-pulse combination (MPC) [7,8]. For the filtering approach, the HFWG output signal is coupled to and filtered by a pulse shaping filter so that the resultant signal can meet the spectrum regulations.…”

Abstract-A low-power on-off-keying impulse-radio (IR) ultra-wideband (UWB) pulse generator (PG) intended for wireless-powered IR-UWB radio applications is presented. The proposed PG has high flexibility, the center frequency, output power and pulse-width (PW) are controllable depending on channel conditions and data rates. Qualitative frequency-domain and transient analyses are presented. A new figure-of-merit (FoM) is proposed such that a more precise comparison between different PGs can be made. The PG is successfully implemented in a TSMC 90 nm CMOS process, measurements show the energy consumption and FoM to be 2.8-7.5 pJ/pulse and 1.6-2.6% respectively. The output swing and PW are 277-329 mV p-p and 509-1088 ps respectively. The core area is 0.092 mm 2 .
