Adaptive MIMO Channel Estimation using Sparse Variable Step-Size NLMS Algorithms
Guan Gui, Li Xu, Lin Shan +1
To estimate multiple-input multiple-output (MIMO) channels, invariable step-size normalized least mean square (ISSNLMS) algorithm was applied to adaptive channel estimation (ACE).…
Extra Gain:Improved Sparse Channel Estimation Using Reweighted l_1-norm Penalized LMS/F Algorithm
Guan Gui, Li Xu, Fumiyuki Adachi
The channel estimation is one of important techniques to ensure reliable broadband signal transmission. Broadband channels are often modeled as a sparse channel. Comparing with tra…
RZA-NLMF algorithm based adaptive sparse sensing for realizing compressive sensing problems
Guan Gui, Li Xu, Fumiyuki Adachi
Nonlinear sparse sensing (NSS) techniques have been adopted for realizing compressive sensing in many applications such as Radar imaging. Unlike the NSS, in this paper, we propose…
Compressive sensing based Bayesian sparse channel estimation for OFDM communication systems: high performance and low complexity
Guan Gui, Li Xu, Lin Shan +1
In orthogonal frequency division modulation (OFDM) communication systems, channel state information (CSI) is required at receiver due to the fact that frequency-selective fading ch…
