Estimators with continuous and discrete parameters

Robby McKilliamPost DocInstitute for Telecommunications Research at the University of South Australia, Adelaide

We consider estimation problems where some of the parameters come from a continuous set, such as the set of real numbers, and other parameters come from a discrete set, such as the set of integers. Some specific applications where estimators of this type arise are considered: direction estimation, period estimation from sparse observations, and noncoherent detection of communications signals. In each case we derive the asymptotic statistical properties of the estimators, and develop fast algorithms for their computation. Concepts from the geometry of numbers and techniques for the analysis empirical processes are involved.
