The project has successfully demonstrated reduced-rank, space-time equalization for high-speed wireless digital communications capable of reliably transmitting multimedia data in support of military operations in stressful environments involving multipath propagation. Research conducted as part of this effort was recognized by a number of awards including a Technical Achievement Award and a Distinguished Lecturer appointment from the IEEE Signal Processing Society, and two Best Paper Awards from the IEEE Communications Society. A key finding that fueled a number of innovations towards the end of the three-year effort was that adding a stage to the Multi-Stage Wiener Filter was exactly equivalent to taking a step of a Conjugate-Gradient CG search. A key innovation was the formulation of the matrix-vector product in the CG algorithm in terms of low-complexity FFTs for reduced computation and storage requirements. The results of this research was published extensively in a number of high-profile IEEE and SPIE conferences.
