Signal Processing

The technology of beamforming is key to many applications in signal processing such as radars and cell phone transmission.

It arises when a signal impinges upon an array of sensors. The operator needs to find the linear combination of sensor outputs that captures the desired signal with minimum noise.

This requires an estimate of the covariance matrix of sensor noise. When there are many sensors in the array, this covariance matrix is large. This is when the proprietary technology of Studdridge International delivers a significant boost in performance.
