Rapidly Varying Sparse Channel Tracking with Hybrid Kalman-OMP Algorithm
It is expected from future communication standards that channel estimation algorithms should be able to operate over very fast varying frequency selective channel models. Therefore in this study autoregressive (AR) modeled ...
Modeling of Visible Light Channels and Performance Analysis of ACO-OFDM
Spectrum scarcity of traditional radio communication has led communication engineers to find new alternatives. Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated ...
Data-Aided Autoregressive Sparse Channel Tracking for OFDM Systems
In order to meet future communication system requirements channel estimation over fast fading and frequency selective channels is crucial. In this paper Space Alternated Generalized Expectation Maximization Maximum a ...
Channel Estimation for Realistic Indoor Optical Wireless Communication in ACO-OFDM Systems
In this paper channel estimation problem in a visible light communication system is considered. The information data is transmitted using asymmetrical clipped optical orthogonal frequency division multiplexing. Channel ...
