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…
Adaptive Sparse Channel Estimation for Time-Variant MIMO-OFDM Systems
Guan Gui, Wei Peng, Fumiyuki Adachi
Accurate channel state information (CSI) is required for coherent detection in time-variant multiple-input multipleoutput (MIMO) communication systems using orthogonal frequency di…
Sparse Multipath Channel Estimation Using Compressive Sampling Matching Pursuit Algorithm
Guan Gui, Qun Wan, Wei Peng +1
Wideband wireless channel is a time dispersive channel and becomes strongly frequency-selective. However, in most cases, the channel is composed of a few dominant taps and a large…
A Fast Compressive Channel Estimation with Modified Smoothed L0 Algorithm
Guan Gui, Wei Peng, Qun Wan +1
Broadband wireless channel is a time dispersive and becomes strongly frequency selective. In most cases, the channel is composed of a few dominant coefficients and a large part of…
