Low SNR Capacity of Noncoherent Fading Channels
Discrete-time Rayleigh fading single-input single-output (SISO) and multiple-input multipleoutput (MIMO) channels are considered, with no channel state information at the transmit...

Global stabilization of a four rotor helicopter with bounded inputs
Abstract— This paper proposes a global asymptotic stabilizing control law for a quad-rotor helicopter with bounded inputs. The proposed control design exploits the technique base...

On the Topological Complexity of Weakly Recognizable Tree Languages
We show that the family of tree languages recognized by weak alternating automata is closed by three set theoretic operations that correspond to sum, multiplication by ordinals <...

Precise asymptotics for the first moment of the error variance estimator in linear models
Let 2 be the unknown error variance of a linear model and let ^2 be the estimator of 2 based on the residual sum of squares. In this work, we show the precise asymptotics in the l...

A Channel that Heats Up
Motivated by on-chip communication, a channel model is proposed where the variance of the additive noise depends on the weighted sum of the past channel input powers. For this chan...
