RIS-Aided Wireless Communications: Extra Degrees of Freedom via Rotation and Location Optimization
Yajun Cheng, Wei Peng, Chongwen Huang +3
We consider the extra degree of freedom offered by the rotation of the reconfigurable intelligent surface (RIS) plane and investigate its potential in improving the performance of…
Ultra-Dense HetNets Meet Big Data: Green Frameworks, Techniques, and Approaches
Yuzhou Li, Yu Zhang, Kai Luo +3
Ultra-dense heterogeneous networks (Ud-HetNets) have been put forward to improve the network capacity for next-generation wireless networks. However, counter to the 5G vision, ultr…
Improved Channel Estimation with Partial Sparse Constraint for AF Cooperative Communication Systems
Guan Gui, Wei Peng
Accurate channel state information (CSI) is necessary for coherent detection in amplify and forward (AF) broadband cooperative communication systems. Based on the assumption of ord…
Sparse Channel Estimation for Amplify-and-Forward Two-way Relay Network with Compressed Sensing
Guan Gui, Qun Wan, Wei Peng +1
Amplify-and-forward two-way relay network (AFTWRN) was introduced to realize high-data rate transmission over the wireless frequency-selective channel. However, AFTWRC requires the…
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…
