Introduction

Volkan Cevher is an inventor associated with Houston, Texas. His patent work addresses compressive sensing and signal processing methods for estimating the bearings, or directions of arrival, of sparse sources.

Latest Patents

Cevher is associated with 1 patent: “Compressive Sensing System and Method for Bearing Estimation of Sparse Sources in the Angle Domain.” The invention uses randomized projections of sensor data, together with a full waveform recording from a reference sensor, to reconstruct a sparse representation of sources and estimate their number and directions of arrival.

The patent also describes signal-processing techniques for wireless sensor arrays with limited communication bandwidth. In the acoustic bearing-estimation application, source bearings are modeled as a sparse vector in angle space, and functions of low-dimensional microphone-signal projections are used to estimate multiple bearings through an l1-norm minimization problem.
