Low Complexity Sphere Decoding for Spatial Multiplexing MIMO
Vadim Neder, Doron Ezri, Motti Haridim
In this paper we present a novel method for decoding multiple input - multiple output (MIMO) transmission, which combines sphere decoding (SD) and zero forcing (ZF) techniques to p…

The exit problem in optimal non-causal extimation
Doron Ezri, Ben-Tzion Bobrovsky, Zeev Schuss
We study the phenomenon of loss of lock in the optimal non-causal phase estimation problem, a benchmark problem in nonlinear estimation. Our method is based on the computation of t…

About the true type of smoothers
D. Ezri, B. Z. Bobrovsky, Z. Schuss
We employ the variational formulation and the Euler-Lagrange equations to study the steady-state error in linear non-causal estimators (smoothers). We give a complete description o…
