Joint channel tracking and symbol detection for OFDM systems with Kalman filtering
(Urban & Fischer Verlag, 2003)
This paper proposes a new joint channel tracking and symbol detection scheme for pilot symbol-assisted OFDM systems in multipath fading. The proposed scheme uses Kalman filters for both channel tracking and subsequent ...
Range sensing with a Scheimpflug camera and a CMOS sensor/processor chip
(IEEE-INST Electrical Electronics Engineers Inc, 2004-02)
An image-based range-sensing technique is presented. The technique is originally considered for highway collision avoidance applications, but its generality makes it suitable for application in robotics, manufacturing, and ...
Maximum a posteriori multipath fading channel estimation for OFDM systems
(Assoc Elettrotecnica Ed Elettronica Italiana, 2002-10)
In this paper, a non-data-aided maximum a posteriori (MAP) channel estimation technique for OFDM systems employing M-PSK modulation scheme is proposed. The technique requires a convenient representation of the discrete ...
Dynamical analysis of uncertain neural networks with multiple time delays
(Taylor & Francis Ltd, 2016-02-17)
This paper investigates the robust stability problem for dynamical neural networks in the presence of time delays and norm-bounded parameter uncertainties with respect to the class of non-decreasing, non-linear activation ...
Confluent edge conditions for the electromagnetic wave at the edge of a wedge bounded by material sheets
(Elsevier ScienceWave Motion, 2000-07)
The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges. In analytical studies they ...
Significance map pruning and other enhancements to SPIHT image coding algorithm
(Elsevier Science, 2003-10)
This paper proposes several enhancements to the Set Partitioning in Hierarchical Trees (SPIHT) image coding algorithm without changing the original algorithm's general skeleton. First and foremost, a method for significance ...
Influence of the velocity on the energy patterns of moving scatterers
(Taylor & Francis, 2004)
Parallel to the developments in the communication through space vehicles achieved during the last two decades, the scattering problems connected with moving objects became more and more important from both theoretical and ...
End-effector trajectory control in a two-link flexible manipulator through reference joint angle values modification by neural networks
(Sage Publications, 2006-02)
The basic difficulty in the control of flexible link manipulators stems from the fact that the link deflections cannot be controlled directly. Since the number of control inputs, applied by the actuators, is less than the ...
Non-data-aided ML carrier frequency and phase synchronization in OFDM systems
(Wiley-Blackwell, 2001-04)
In this paper non-data-aided(NDA), maximum likelihood(ML) algorithms are derived for the carrier frequency and phase offset, separately, for OFDM systems employing M-PSK modulation scheme. NDA ML estimation algorithm for ...
On the performance of trellis coded M-PSK systems over Rician fading channels with phase jitter
(Assoc Elettrotecnica Ed Elettronica Italiana, 2001-02)
In this paper, the performance of trellis coded M-PSK systems is investigated operating over Rician fading channels with phase jitter. Thus the results reflect not only the degradation due to the effect of fading on the ...
