Space time block code classification for MIMO signals exploiting cyclostationarity
(Institute of Electrical and Electronics Engineers Inc, 2015)
Blind and noncooperative identification of the transmission parameters of unknown communication signals has been employed both in military and civilian applications. Multiple-Input-Multiple-Output (MIMO) transmission systems ...
Joint space time block code and modulation classification for MIMO systems
(Institute of Electrical and Electronics Engineers Inc, 2017-02)
Non-cooperative identification of unknown communication signals is a popular research area with widespread civilian and military applications. Multiple input multiple output (MIMO) systems employing multi-antenna transmission ...
Modulational instability of acoustic waves in a dusty plasma with nonthermal electrons and trapped ions
(Pergamon-Elsevier Science Ltd, 2019-04)
In the present work, employing the nonlinear field equations of a hot dusty plasma in the presence of nonthermal electrons and trapped ions, we studied the amplitude modulation of nonlinear waves in such a plasma medium ...
Cyclostationarity based blind block timing estimation for alamouti coded MIMO signals
(IEEE, 2017-06)
Blind parameter estimation algorithms provide a powerful tool for application scenarios where the use of training or pilot sequences is not desirable, e.g., in order to improve the bandwidth efficiency of the transmission, ...
Modulation of cylindrical (spherical) waves in a plasma with vortex electron distribution
(American Institute of Physics Inc., 2018-07-01)
In the present work, employing cylindrically (spherically) symmetric field equations of a plasma consisting of a cold electron fluid, hot electrons obeying a trapped/vortex-like distribution and stationary ions, we studied ...
Coupled quintic nonlinear Schrodinger equations in a generalized elastic solid

In the present study, the nonlinear modulation of transverse waves propagating in a cubically nonlinear dispersive elastic medium is studied using a multiscale expansion of wave solutions. It is found that the propagation ...
Two-dimensional wave packets in an elastic solid with couple stresses
(Pergamon-Elsevier Science Ltd, 2004-08)
The problem of (2+1) (two spatial and one temporal) dimensional wave propagation in a bulk medium composed of an elastic material with couple stresses is considered. The aim is to derive (2+1) non-linear model equations ...
Non-linear waves in a viscous fluid contained in an elastic tube with variable cross-section
