Variance detection for non-coherent impulse radio UWB receivers

2014 International Conference on Computing, Networking and Communications (ICNC), 2014
In this paper, a novel detection algorithm based on variance detection (VD) is proposed for non-coherent impulse radio (IR) ultra-wideband (UWB) receivers. In the VD-based detection algorithm, after the received IR UWB signals are squared, their variance instead of their mean is measure to recover information bits.

Ring-coupled chaotic generator for coherent and non-coherent detection

IFAC Proceedings Volumes, 2013
Abstract This paper deals with chaotic encryption and observer synthesis for coherent detection using a new ring-coupled map firstly introduced by Lozi. The specificity of the switched map under investigation is that it exhibits excellent properties for chaotic encryption, but has no standard solution for the observer design.

Non-Coherent Multiple-Symbol Detection for Diffusive Molecular Communications

Proceedings of the 3rd ACM International Conference on Nanoscale Computing and Communication, 2016
Most of the available works on molecular communication (MC) assume that the channel state information (CSI) is perfectly known at the receiver for data detection. In contrast, in this paper, we study non-coherent multiple-symbol detection schemes which do not require knowledge of the CSI.

Improvements of IEEE 802.15.4a for non-coherent energy detection receiver

2012 International Symposium on Signals, Systems, and Electronics (ISSSE), 2012
Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Moreover, it is able to offer accurate localization in the range of few centimeters. Regarding these qualities, it is desirable to design an IR-UWB transceiver which consumes as little power as possible ...

Efficient non-coherent detection techniques for broadband cooperative networks

2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS), 2013
Research on non-coherent detection for cooperative communications is at an early stage and many fundamental problems are still open. We will be working on an important open problems in broadband cooperative wireless communications. A novel non-coherent detection scheme for a multi-relay cooperative orthogonal frequency division multiplexing (OFDM ...

Non-coherent multi-user detection based on quantum search

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
3G and 4G mobile systems are based on CDMA technology. In order to increase the efficiency of CDMA receivers a large amount of effort is invested to develop suitable multi-user detector techniques. However, at this moment there are only suboptimal solutions available because of the rather high complexity of optimal detectors.

An energy detection receiver for non-coherent IR-UWB

Journal of Semiconductors, 2011
A non-coherent receiver for impulse radio ultra-wide band (IR-UWB) is presented. The proposed receiver front-end consists of a high gain LNA, a high frequency detector and an intermediate frequency (IF) amplifier to amplify the recovered signal and drive an external test instrument.

Non-coherent detection for DS spread-spectrum acquisition

MILCOM 92 Conference Record, 2003
Noncoherent detectors for initial code synchronization (acquisition) of binary- and quarternary-phase-shift-keying (BPSK and QPSK) direct-sequence (DS) spread-spectrum signals are analyzed. In addition to the thermal noise, in many applications such detectors are faced with self-noise due to imperfect correlations.

Improved detection scheme for non-coherent UWB communications

2016 8th International Conference on Ultrawideband and Ultrashort Impulse Signals (UWBUSIS), 2016
An improved detection scheme is proposed for noncoherent impulse radio ultra-wideband (IR-UWB) receivers. The peak amplitude of impulse and RMS value of noise are considered as detection parameters in the proposed method. The receiver based on this method, unlike conventional energy detection (ED) based receivers, does not collect the energy and uses ...

Non-coherent MLSE detection for CDMA multiple-antenna systems

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
Non-coherent detection of DS-CDMA signals which make use of M-DPSK modulation in presence of antenna arrays is considered. Firstly, the optimum non-coherent MLSE detection rule is derived for a K dimension DS-CDMA vectorial channel assuming perfect single-user beamforming.
