| Popis: | In this paper we are interested in the problem of the estimation of polynomial phase signals affected by a multiplicative noise and an additive noise using the high-order ambiguity function. We distinguish for the multiplicative noise the non-zero mean case and the zero mean case. We analyse the performances of the proposed estimators and compare their respective variances with the corresponding Cramer–Rao bounds. The theoretical results are illustrated by computer simulations. |
