Effects of channel state information uncertainty on the performance of stochastic signaling

Göken, Çağrı; Gezici, Sinan; Arıkan, Orhan (IEEE, 2011)

In this paper, stochastic signaling is studied for power-constrained scalar valued binary communications systems in the presence of uncertainties in channel state information (CSI). First, it is shown that, for a given ...

Extraction of sparse spatial filters using Oscillating Search

Onaran, İbrahim; İnce, N. Fırat; Abosch, A.; Çetin, A. Enis (IEEE, 2012)

Common Spatial Pattern algorithm (CSP) is widely used in Brain Machine Interface (BMI) technology to extract features from dense electrode recordings by using their weighted linear combination. However, the CSP algorithm, ...

Particle swarm optimization for SAGE maximization step in channel parameter estimation

Bodur, Harun; Tunç, Celal Alp; Aktaş, Defne; Ertürk, Vakur .B.; Altıntaş, Ayhan (IET, 2007-11)

This paper presents an application of particle swarm optimization (PSO) in space alternating generalized expectation maximization (SAGE) algorithm. SAGE algorithm is a powerful tool for estimating channel parameters like ...

Stochastic signaling in the presence of channel state information uncertainty

Goken, C.; Gezici, S.; Arikan, O. (Elsevier, 2013)

In this paper, stochastic signaling is studied for power-constrained scalar valued binary communications systems in the presence of uncertainties in channel state information (CSI). First, stochastic signaling based on the ...
