Estimation and Detection of Subspace Signals in Subspace Interference and Noise

Prof. John A. Gubner
UW ECE Dept.

Abstract

Oblique pseudoinverses and oblique projections arise naturally in the estimation and detection of subspace signals measured in the presence of subspace interference and broadband noise. By and large, the existing theory for such problems has been developed for finite-dimensional measurement spaces. However, the natural models of multi-access communication and modern radar and sonar systems involve infinite-dimensional waveform spaces. In this talk, we extend the concepts of oblique pseudoinverse and oblique projection to arbitrary inner product spaces. We use these results to solve the aforementioned estimation and detection problems in the continuous-time setting.

This is joint work with Louis L. Scharf.
