Correlation-Aware Greedy User Grouping for Zero-Forcing Precoding in Massive MIMO Downlink Systems

Massive multiple-input multiple-output (MIMO) systems achieve high spectral efficiency through spatial multiplexing, where zero-forcing (ZF) precoding is widely adopted due to its effective interference suppression and moderate computational complexity. However, the performance of ZF precoding is highly dependent on us...

A Sparse-Aware Variable Step-Size NLMS Equalizer with Dynamic Reweighted Regularization for Time-Varying Multipath Channels

Sparse adaptive equalization is widely used for time-varying multipath channels due to its ability to exploit channel sparsity and reduce computational complexity. However, conventional normalized least mean square (NLMS)-based algorithms usually rely on fixed step-size strategies or manually selected regularization pa...
