A Low-Power, Low Data-Rate, Ultra-Wideband Receiver Architecture for Indoor Wireless Systems

Pierre-André Farine, Cyril Botteron, Christian Robert, Frédéric Chastellain, Uroschanit Yodprasit, Alexander Heubi, Paul Saad

Abstract—In this paper, a novel architecture for a low data-rate, low power consumption Impulse Radio (IR) Ultra- Wideband (UWB) receiver is presented in which the received UWB signal is downconverted to a given intermediate frequency (IF) rather than at b ...

Broadcast, relay and feedback in Gaussian channels

Sibi Raj Bhaskaran Pillai

Network information theory explores the fundamental data transport limits over communication networks. Broadcasting and relaying are two natural models arising in communication contexts where multiple users share a common communication medium. Number of re ...

Convergence analysis for sequential Monte Carlo receivers in communications applications

Volkan Cevher

Recently, sequential Monte Carlo methods have been used in the telecommunications field, finding application in receiver design. Several properties of these receivers make their designs very attractive. These receivers do not require channel state informat ...

On Successive Refinement of Diversity for fading ISI channels

Suhas Diggavi, Sanket Dusad

Abstract—Rate and diversity impose a fundamental tradeoff in communications. This tradeoff was investigated for IntersymbolInterference (ISI) channels in [4]. A different point of view was explored in [1] where high-rate codes were designed so that they ha ...

A phase noise compensation scheme for OFDM wireless systems

Ali H. Sayed

Phase noise causes significant degradation in the performance of Orthogonal Frequency Division Multiplexing (OFDM) based wireless communication systems. In the proposed compensation scheme, the communication between the transmitter and receiver blocks cons ...

Adaptive Subchip Multipath Resolving for Wireless Location Systems

Ali H. Sayed

Reliable positioning of cellular users in a mobile environment requires accurate resolving of overlapping multipath components. However, this task is difficult due to fast channel fading conditions and data ill-conditioning, which limit the performance of ...

Advanced OFDM systems for terrestrial multimedia links

Renzo Posega

Recently, there has been considerable discussion about new wireless technologies and standards able to achieve high data rates. Due to the recent advances of digital signal processing and Very Large Scale Integration (VLSI) technologies, the initial obstac ...

Efficient error correction solutions for OFDM based digital video

Mauro Lattuada

The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...

On Embedded Diversity Codes

Suhas Diggavi, Sanket Dusad

Diversity-embedded codes for fading channels are high-rate codes that are designed so that they have a high-diversity code embedded within them \cite{DIMACS,Embed:Globecom}. This is equivalent to coding the data into two streams such that the high-priority ...

LDPC codes for Gaussian broadcast channels

Peter Allan Berlin, Daniela Tuninetti

We study coding over a class of two-user broadcast channels with additive white Gaussian noise and fading known at the receivers only. Joint decoding of low-density parity-check codes is analyzed. The message update rule at the mapping node linking the use ...
