A 0.13μm CMOS Gm-C LPF for UWB receiver
2007 Edition, October 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A 264 MHz 6th order Gm-C Chebyshev low-pass filter based on the leapfrog structure for direct conversion UWB receiver is presented. The universal design flow and the topology of this filter are also analyzed. Tuning capacitors digitally and tuning the...

UWB receiver performance comparison
2004 Edition, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The BER performance of the imperfect matched filter (IMF) is compared to the BER performance of the transmit reference (TR) receiver. Imperfect channel estimation is taken into account. The resulting BER performance of the IMF receiver is compared to the BER performance of the TR...

An oversampled channelized UWB receiver
2004 Edition, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To digitize the ultra-wideband (UWB) signal at its Nyquist rate, a frequency channelized receiver for UWB radio based on hybrid filter banks (HFB) is presented. Among the challenges of such receivers are the uncertainties of the analog analysis filters and...

A WiMedia UWB receiver with a synthesizer
2008 Edition, September 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper describes a direct-conversion receiver for WiMedia UWB applications. The receiver consists of separate BG1 and BG3 LNAs including a 2.4-GHz notch filter, quadrature mixers, a base-band gm-C low-pass filter with variable gain,...

An Analog DS-UWB receiver
2007 Edition, September 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose a direct-conversion direct-sequence inductorless CMOS receiver for pulse-based UWB communications using a high-speed analog Viterbi decoder. The circuit system architecture is presented and simulation results for a...

A New Transmitted Reference Based UWB Receiver
2010 Edition, Volume 3, April 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The Transmitted-Reference (TR) signaling scheme, in conjunction with Autocorrelation Receivers (AcR), has received much attention as the low complexity architecture for Ultra Wide Band (UWB) communications system. Due to the usage of the noisy received signal as the correlate...

Pulse shaping optimizer in UWB receivers
2005 Edition, Volume 2A, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In coherent UWB receivers, creating a template to match the received signal exactly is usually difficult and costly. If a simplified template is employed, the receiver's performance degrades due to the unmatched template. The paper proposes a pulse shaping...

Fast Acquisition in Coherent UWB Receivers
2006 Edition, Volume 10, June 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Synchronization is a key issue for ultra-wideband (UWB) radios. Coherent UWB receivers, which correlate the received signal with a well-designed template, have very stringent requirements for synchronization accuracy, leading to a long...

Real time reconfigurability for UWB receiver
2008 Edition, Volume 1, September 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Real time reconfigurability of the digital backend of UWB receiver has a potential to achieve significant power saving during the acquisition and synchronisation mode of receiver operation. This paper proposes a novel real time reconfigurability algorithm which...

Acquisition for a transmitted reference UWB receiver
2008 Edition, Volume 2, September 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

An acquisition algorithm for a transmitted reference (TR) ultra wideband (UWB) receiver is developed that uses the statistical properties of TR-UWB signals to distinguish between noise and data, achieve acquisition and ignores or decodes the incoming samples...
