Cube-Split: Structured Quantizers on the Grassmannian of Lines
Alexis Decurninge, Maxime Guillaud
This paper introduces a new quantization scheme for real and complex Grassmannian sources. The proposed approach relies on a structured codebook based on a geometric construction o…
SNOPS: Short Non-Orthogonal Pilot Sequences for Downlink Channel State Estimation in FDD Massive MIMO
Beatrice Tomasi, Alexis Decurninge, Maxime Guillaud
Channel state information (CSI) acquisition is a significant bottleneck in the design of Massive MIMO wireless systems, due to the length of the training sequences required to dist…
Channel Covariance Estimation in Massive MIMO Frequency Division Duplex Systems
Alexis Decurninge, Maxime Guillaud, Dirk Slock
Channel covariance is emerging as a critical ingredient of the acquisition of instantaneous channel state information (CSI) in multi-user Massive MIMO systems operating in frequenc…
Robust Burg Estimation of Radar Scatter Matrix for Autoregressive structured SIRV based on Fréchet medians
Alexis Decurninge, Frédéric Barbaresco
We address the estimation of the scatter matrix of a scale mixture of Gaussian stationary autoregressive vectors. This is equivalent to consider the estimation of a structured scat…
