Cramer–Rao Lower Bound for Constrained Complex Parameters
... HE CRAMER–RAO lower bound (CRB) serves as an important tool in the performance evaluation of estimators which arise frequently in the fields of communications and signal processing. Most problems involving the CRB are formulated in terms of unconstrained real parameters [1]. Two useful developments ...

... perpendicular to the paper) is defined as the magnitude of the force times its arm which is the perpendicular distance between the axis of rotation and the line of action of force; that is t = Fr sin q = |r × F|. Thus r × F represents the torque of F about an axis through O and perpendicular to the ...

... 1.3, 13 Establish that if the set {v1 , v2 , v3 } is linearly independent, then so is {v1 + v2 , v2 + v3 , v3 + v1 }. Proof. We’ll do this using the contrapositive. Thus, assume that {v1 + v2 , v2 + v3 , v3 + v1 } is linearly dependent. By definition, this means we can find a1 , a2 , a3 ∈ R such tha ...
