Estimation of Ambiguity Functions With Limited Spread
Hindberg, Heidi; Olhede, Sofia C. (Research report; Forskningsrapport, 2008-04-07)This paper proposes a new estimation procedure for the ambiguity function of a non-stationary time series. The stochastic properties of the empirical ambiguity function calculated from a single sample in time are derived. Different thresholding procedures are introduced for the estimation of the ambiguity function. Such estimation methods are suitable if the ambiguity function is only non-negligible ...
