Effective Low-Complexity Optimization Methods for Joint Phase Noise and Channel Estimation in OFDM
Zhongju Wang, Prabhu Babu, Daniel P. Palomar
Phase noise correction is crucial to exploit full advantage of orthogonal frequency division multiplexing (OFDM) in modern high-data-rate communications. OFDM channel estimation wi…
Design of PAR-Constrained Sequences for MIMO Channel Estimation via Majorization-Minimization
Zhongju Wang, Prabhu Babu, Daniel P. Palomar
PAR-constrained sequences are widely used in communication systems and radars due to various practical needs; specifically, sequences are required to be unimodular or of low peak-t…
Orthogonal Sparse PCA and Covariance Estimation via Procrustes Reformulation
Konstantinos Benidis, Ying Sun, Prabhu Babu +1
The problem of estimating sparse eigenvectors of a symmetric matrix attracts a lot of attention in many applications, especially those with high dimensional data set. While classic…
