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.
Time and Place: Wed., Sept. 22, 3:30-4:30 pm in 4610 Engr. Hall.
