A frame-start detector for a 4 x 4 MIMO-OFDM system
Future wireless LANs will increase the peak data rate by employing multiple antennas at both transmitter and receiver. ...
Ieee Service Center, 445 Hoes Lane, Po Box 1331, Piscataway, Nj 08855-1331 Usa2006Belief Propagation Decoding for Codes Based on Discretized Chaotic Maps
In this paper a class of discretized piecewise linear chaotic maps of a very high dimensions are used for communication over a noisy channel. An information payload that is sent over a channel is controlled in the transmitter and is related to the symbolic ...
2006Efficient error correction solutions for OFDM based digital video
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 ...
EPFL2005Classification of chaotic sequences with open-loop estimator - Optimal design for noisy environments
Martin Hasler, Thomas Schimming
In this paper, an approach based on ergodic properties for classifying sequences is given. It is particularly robust due to the open loop structure of the detector. Unlike previous works in this direction, such as those concerning the inverse system approa ...
2004Space-time coding in MISO-OFDM systems with implementation impairments
Implementation of OFDM-based systems suffers from in-phase and quadrature-phase (IQ) imbalances in the front-end analog processing. The resulting distortion due to IQ imbalances can limit the achievable operating SNR at the receiver, especially when space- ...
IEEE2004Coded Modulations Using Chaotic Systems Controlled by Small Perturbations
Martin Hasler, Thomas Schimming, Kumiko Oshima
Recently it has been observed that communications using chaos show best performance if the information production related to the chaos in the transmitter is controlled and used for the payload of the communication \cite{Schimming:Nolta:2002}. In the case o ...
2002Modeling and classification of approximately periodic signals using chaotic systems
A new chaos-based technique for modeling the diversity of approximately periodic signals is introduced and exploited, combined with generalized chaotic synchronization phenomena, for the solution of temporal pattern recognition problems ...
2002Modeling diversity by strange attractors with application to temporal pattern recognition
This thesis belongs to the general discipline of establishing black-box models from real-word data, more precisely, from measured time-series. This is an old subject and a large amount of papers and books has been written about it. The main difficulty is t ...
EPFL2001Synchronization of two-dimensional chaotic dynamic systems by the transmission of state information
Chaotic synchronization is treated within the framework of information theory. It is shown that information theory implies fundamental limits to chaotic synchronization in the presence of channel noise. With regard for these limits, a scheme is suggested f ...
2000Adaptive multi-input multi-output fading channel equalization using Kalman estimation
Ali H. Sayed, Christina Fragouli
This paper derives new tracking results for adaptive filtering algorithms operating in the presence of two sources of non-stationarities: a carrier
frequency offset and random variations. Both impairments are common in digital communications due to varia ...
