Multiband orthogonal frequency division multiplexing for ultra-wideband wireless communication: analysis, extensions and implementation aspects
… Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB for high data-rate communication. We address four main questions: (1) What are the theoretical performance limits and practical system performance of MB-OFDM? (2) What extensions can be used to increase the system power efficiency and …

Enabling Blocks for Integrated CMOS UWB Transceivers
… with the circuit design of enabling blocks for MB-OFDM UWB CMOS single-chip transceivers, namely the frequency synthesizer and the transmission mixer and power amplifier. First we discuss three different models for the simulation of chargepump phase-locked loops, namely the continuous time …

Design of RF CMOS Power Amplifier for UWB Applications
… challenging task. Two proposals- Multi-Band OFDM and Direct-Sequence CDMA have been put before the IEEE 802.15.3a task group to decide on the industry standard for the commercial deployment of this technology. Though the debate on which standard is better has not been resolved, proponents of …

Correlator for a Basis-Space Architecture Ultra-Wideband Receiver
… orthogonal frequency division multiplexing (MB-OFDM).Architecture development for the integrator begins with a comparison of ideal integration versus circuit limited real integration. Ideal integration relies on infinite DC gain and constant phase shift to operate. Real integration is …
