Detection of Jamming Attack in Non-Coherent Massive SIMO Systems

IEEE Transactions on Information Forensics and Security, 2019
In recent studies, a simple non-coherent communication scheme based on energy detection is proposed in massive single-input multiple-output (SIMO) systems. Before data transmission, the transmitter sends pilots to the receiver for the purpose of estimating the channel statistics.

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.

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 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.

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.

A unifying perspective of coherent and non-coherent change detection

SPIE Proceedings, 2014
In this paper we present a new generalized family of change detection algorithms for SAR imagery that includes traditional non-coherent and coherent processing as special cases. The parameterized family of algorithms, referred to as partially coherent change detection (PCCD), allows the user to select the level of coherence desired in the change ...
