The optimal power adaptation problem is investigated for vector parameter\nestimation according to various Fisher information based optimality criteria.\nBy considering an observation model that involves a linear transformation of\nthe parameter vector and an additive noise component with an arbitrary\nprobability distribution, six different optimal power allocation problems are\nformulated based on Fisher information based objective functions. Via\noptimization theoretic approaches, various closed-form solutions are derived\nfor the proposed problems. Also, the results are extended to cases in which\nnuisance parameters exist in the system model or certain types of nonlinear\ntransformations are applied on the parameter vector. Numerical examples are\npresented to investigate performance of the proposed power allocation\nstrategies.\n
