Time-domain Beam Shaping of Pulsed Arrays
Pulsed arrays are becoming popular in new Ultra-wideband applications to enhance the robustness of transmitted and received signals in complex environments and to identify the angle of arrival of multiple echoes. A global synthesis technique is here proposed to shape the array field in accordance to a given angle-time mask. The synthesis problem is cast as the inverse Radon transform of a desir...
متن کاملTime-domain Beamforming using 3D-microphone arrays
Acoustic measurements inside any cavity are mostly conducted with a view number of microphones. By this means it is possible to gain information about frequencies, orders, sound pressures. However, a space selective analysis is nearly impossible and it is not feasible to find multiple sound sources position in space in a practical way. Traditional beam forming systems with planar microphone arr...
متن کاملTime domain constrained H ∞ - synthesis
StructuredH∞-synthesis subject to time domain performance specifications is introduced. Our method allows to control trajectories of the linearized system and the underlying nonlinear dynamics simultaneously. A non-smooth bundle optimization method for this class of programs is proposed and discussed. Our approach is tested against two benchmark studies: control of a rotational actuator to atte...
متن کاملEmotions in time domain synthesis
1.2 Resynthesis A preliminary test exploring 4 emotions showed that conveying emotions by time domain synthesis may be possible. Therefore, a more sophisticated test was carried out in order to determine the influence of the prosodic parameters in the perception of a speaker's emotional state. Six different emotional states were investigated. The stimuli of the second test were used in three di...
متن کاملTerahertz pulsed time-domain holography and iterative phase retrieval methods
We present latest results obtained in the scope of imaging methods which allows one to recover spatial phase distribution in the terahertz wave-fields. One of these methods is the terahertz pulse time-domain holography. The second one is the iterative phase retrieval approach, transferred from the visible frequency range.
