A 0.17-nJ/Pulse IR-UWB Receiver Based on Distributed Pulse Correlator in 0.18-μm Digital CMOS

This paper presents a low power impulse-radio ultra-wideband (IR-UWB) receiver based on a reconfigurable, high speed analog correlator called distributed pulse correlator (DPC). The DPC incorporates built-in local template pulse generation, and hence significantly reduces the power consumption and circuit complexity of the analog correlation receiver. A chip prototype of the IR-UWB receiver was...

Performance Evaluation of Coded UWB-IR on Multipath Fading Channels

In most research on error correction coding for UWB techniques, the channel is assumed to be Gaussian, whereas the multipath case is neglected. In this paper, we evaluate the performance of a realistic and feasible UWB-IR system in a severe multipath environment. We model the nonlinearities introduced by UWB antennas, by using their real characteristics obtained through the measurements. We pre...

A two-stage acquisition scheme based on multiple correlator outputs for UWB signals

In ultra-wideband (UWB) channels, the signal energy in the acquisition receiver spreads over correlator outputs due to rich multipaths, making the output of each correlator have only a small portion of the total energy. To enhance the acquisition performance for UWB signals by exploiting the signals spread over a number of correlator outputs, this paper proposes a two-stage acquisition scheme. ...

Multi-Delay Biorthogonal Coded/Balanced TR-UWB Receiver for WPAN Based on Hadamard Matrix

Impulse radio ultra wideband (IR-UWB) communication is becoming an important technology for future Wireless Personal Area Networks (WPANs). One of the critical challenges in IR-UWB system design is the inter-pulse interference (IPI). A Transmit-reference (TR) receiver is proposed to completely remove the IPI especially at low input frame energy-tonoise-ratio (Ef/No) values. This receiver is bas...

Modified MSSNR Based Channel Shortening for UWB Receiver Design Simplification

Ultra wide band (UWB) propagation channels are highly rich in multipaths. A major problem encountered in UWB systems is to capture enough multipaths to maintain a sufficient signal to noise ratio (SNR) for further signal processing. This leads to a RAKE receiver with large number of fingers. Channel shortening can help in simplifying the RAKE receiver architecture by reducing the channel taps. ...
