Subspace Tracking and Least Squares Approaches to Channel Estimation in Millimeter Wave Multiuser MIMO

open access: yes, 2019
The problem of MIMO channel estimation at millimeter wave frequencies, both in a single-user and in a multi-user setting, is tackled in this paper. Using a subspace approach, we develop a protocol enabling the estimation of the right (resp.

The coevolution of board interlock networks and corporate strategic actions

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Studies on board interlock networks are divided into two streams, one examining their dynamics; the other, their consequences. We propose that both phenomena—board interlock dynamics and consequences—are interdependent. Applying structuration theory, we explain and empirically demonstrate how firms' corporate strategic actions
