This paper presents several approximate formulas for the Wiener filter (WF), the optimal linear filter minimizing the mean-squared error. Compared to the WF, our formulas do not directly involve inverting the observation covariance matrix. An important consequence is that our approximate filters do…
One measure of the global fault tolerance of a redundant robot is the size of its self-motion manifold. If this size is defined as the range of its joint angles, then the optimal self-motion manifold size for an n-degree-of-freedom (DoF) robot is n × 2π, which is not typical for existing robot desig
We develop polynomial-time heuristic methods to solve unimodular quadratic programming (UQP) approximately, which is known to be NP-hard. In the UQP framework, we maximize a quadratic function of a vector of complex variables with unit modulus. Several problems in active sensing and wireless communi…
