High Accuracy Distributed Kalman Filtering for Frequency and Phase Synchronization in Distributed Phased Arrays
Mohammed Rashid, Jeffrey A. Nanzer
Precise frequency and phase synchronization are among the important aspects in a coherent distributed phased array antenna system, and are among the most challenging to achieve for…
Online Expectation-Maximization Based Frequency and Phase Consensus in Distributed Phased Arrays
Mohammed Rashid, Jeffrey A. Nanzer
Distributed phased arrays are comprised of separate, smaller antenna systems that coordinate with each other to support coherent beamforming towards a destination. However, due to…
A Message Passing Based Average Consensus Algorithm for Decentralized Frequency and Phase Synchronization in Distributed Phased Arrays
Mohammed Rashid, Jeffrey A. Nanzer
We consider the problem of decentralized frequency and phase synchronization in distributed phased arrays via local broadcast of the node electrical states. Frequency and phase syn…
Frequency and Phase Synchronization in Distributed Antenna Arrays Based on Consensus Averaging and Kalman Filtering
Mohammed Rashid, Jeffrey A. Nanzer
A decentralized approach for joint frequency and phase synchronization in distributed antenna arrays is presented. The nodes in the array share their frequencies and phases with th…
Clustered Sparse Channel Estimation for Massive MIMO Systems by Expectation Maximization-Propagation (EM-EP)
Mohammed Rashid, Mort Naraghi-Pour
We study the problem of downlink channel estimation in multi-user massive multiple input multiple output (MIMO) systems. To this end, we consider a Bayesian compressive sensing app…
Semi-blind Channel Estimation and Data Detection for Multi-cell Massive MIMO Systems on Time-Varying Channels
Mort Naraghi-Pour, Mohammed Rashid, Cesar Vargas-Rosales
We study the problem of semi-blind channel estimation and symbol detection in the uplink of multi-cell massive MIMO systems with spatially correlated time-varying channels. An algo…
