Near-field channel estimation via wavefront parameterization
Heedong Do, Namyoon Lee, Angel Lozano
This paper deals with the estimation of multiantenna channels in the line-of-sight conditions that are prevalent in the near field. By expressing the curved wavefront as a polynomi…

Cramer-Rao Bound for Arbitrarily Constrained Sets
Heedong Do, Angel Lozano
This paper presents a Cramer-Rao bound (CRB) for the estimation of parameters confined to an arbitrary set. Unlike existing results that rely on equality or inequality constraints,…

Beamforming Gain with Nonideal Phase Shifters
Heedong Do, Angel Lozano
This research sets forth a universal framework to characterize the beamforming gain achievable with arbitrarily nonideal phase shifters. Precisely, the maximum possible shortfall r…
