Estimation of FBMC/OQAM Fading Channels Using Dual Kalman Filters
The Scientific World Journal, 2014 We address the problem of estimating time-varying fading channels in filter bank multicarrier (FBMC/OQAM) wireless systems based on pilot symbols. The standard solution to this problem is the least square (LS) estimator or the minimum mean square error ...

Compensating for Channel Fading in DS-CDMA Communication Systems Employing ICA Neural Network Detectors [PDF]
Journal of Systemics, Cybernetics and Informatics, 2005 In this paper we examine the impact of channel fading on the bit error rate of a DS-CDMA communication system. The system employs detectors that incorporate neural networks effecting methods of independent component analysis (ICA), subspace estimation of

Normal approximations for fading channels [PDF]
2018 52nd Annual Conference on Information Sciences and Systems (CISS), 2018 Capacity and outage capacity characterize the maximum coding rate at which reliable communication is feasible when there are no constraints on the packet length. Evaluated for fading channels, they are important performance benchmarks for wireless communication systems. However, the latency of a communication system is proportional to the length of the

Latency and Networking Aspects of Adaptive Modems over Slow Indoors Rayleigh Fading Channels
, 1999 Adaptive modulation exploits the time-variant channel capacity fluctuation of fading channels using a range of different modem modes. Specifically, no information is transmitted when the instantaneous channel signal-to-noise ratio (SNR) is low, and ...

Partial Equalization for MC–CDMA Systems in Non-Ideally Estimated Correlated Fading
, 2010 Multicarrier code-division multiple access (MC–CDMA) can support high data rates in next-generation multiuser wireless communication systems. Partial equalization (PE) is a low-complexity technique for combining the signals of subcarriers to improve the ...

Secret Sharing over Fast-Fading MIMO Wiretap Channels
EURASIP Journal on Wireless Communications and Networking, 2009 Secret sharing over the fast-fading MIMO wiretap channel is considered. A source and a destination try to share secret information over a fast-fading MIMO channel in the presence of an eavesdropper who also makes channel observations that are different ...
