Unlabeled Sensing with Random Linear Measurements
Jayakrishnan Unnikrishnan, Saeid Haghighatshoar, Martin Vetterli
We study the problem of solving a linear sensing system when the observations are unlabeled. Specifically we seek a solution to a linear system of equations y = Ax when the order o…
An Active-Sensing Approach to Channel Vector Subspace Estimation in mm-Wave Massive MIMO Systems
Saeid Haghighatshoar, Giuseppe Caire
Millimeter-wave (mm-Wave) cellular systems are a promising option for a very high data rate communication because of the large bandwidth available at mm-Wave frequencies. Due to th…
Channel Vector Subspace Estimation from Low-Dimensional Projections
Saeid Haghighatshoar, Giuseppe Caire
Massive MIMO is a variant of multiuser MIMO where the number of base-station antennas is very large (typically 100), and generally much larger than the number of spatially mult…
A New Identity for the Least-square Solution of Overdetermined Set of Linear Equations
Saeid Haghighatshoar, Mohammad J. Taghizadeh, Afsaneh Asaei
In this paper, we prove a new identity for the least-square solution of an over-determined set of linear equation , where is an full-rank matrix, is a col…
