"Performance lower bounds of blind system identification techniques in the presence of channel order estimation error"^^ . "In this paper, we derive two performance lower bounds\r\nfor blind system identification in the presence of channel order\r\nestimation error. The first bound deals with models where\r\nboth the channel and unknown symbols are deterministic, and\r\nobtained via the constrained misspecified Cramer-Rao bound\r\n(MCRB). When transmitted symbols are unknown random variables i.i.d. drawn from a stochastic Gaussian process, variance\r\nof any unbiased estimators is always higher than the second\r\nMCRB bound. Both proposed MCRB bounds reduce to the\r\nclassical Cramer-Rao bounds when the channel order is known\r\nor accurately estimated. Besides, the stochastic MCRB is lower than the deterministic bound, especially at high SNRs"^^ . "2021-08" . . . . . . . . . . . . . "Trung Thanh"^^ . "Le"^^ . "Trung Thanh Le"^^ . . "Linh Trung"^^ .
