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 ...

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

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

Wideband Fading Channels With Feedback [PDF]
IEEE Transactions on Information Theory, 2010 The Rayleigh flat fading channel at low SNR is considered. With full channel state information (CSI) at the transmitter and receiver, its capacity is shown to be essentially SNR log(1SNR) nats/symbol, as SNR goes to zero. In fact, this rate can be achieved with a just one bit of CSI at the transmitter (per fading realization) and with no receiver CSI ...

The Streaming-DMT of Fading Channels [PDF]
IEEE Transactions on Information Theory, 2014 We consider the sequential transmission of a stream of messages over a block-fading multi-input-multi-output (MIMO) channel. A new message arrives at the beginning of each coherence block, and the decoder is required to output each message sequentially, after a delay of $T$ coherence blocks.

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 ...
