On stability of generalized phase retrieval and generalized affine phase retrieval

Journal of Inequalities and Applications, 2019
In this paper, we consider the stability of intensity measurement mappings corresponding to generalized phase retrieval and generalized affine phase retrieval in the real case. First, we show the bi-Lipschitz property on measurements of noiseless signals.

Cramer-Rao Bounds and Coherence Performance Analysis for Next Generation Radar with Pulse Trains

Sensors, 2013
We study the Cramer-Rao bounds of parameter estimation and coherence performance for the next generation radar (NGR). In order to enhance the performance of NGR, the signal model of NGR with master-slave architecture based on a single pulse is extended ...

Coherent parameters estimation and coherent performance analysis for distributed aperture coherent radar

Tongxin xuebao, 2015
The closed-form CRB (cramer-rao bounds) of the coherent parameters estimation, which include time delay differences and total phase differences, are derived for the distributed aperture coherent radar with general architecture firstly.

Blind SNR estimation based on cyclostationarity

Tongxin xuebao, 2006
Upsampling and shaping filtering introduce the cyclostationarity of transmit signals. Based on the cyclosta-tionary statistics of signals, a blind SNR estimator in AWGN channel was proposed.

Existence of unbiased estimators in discrete quantum systems

Physical Review Research
The Cramér-Rao bound serves as a crucial lower limit for the mean square error of an estimator in frequentist parameter estimation. Paradoxically, it requires highly accurate prior knowledge of the estimated parameter for constructing the optimal ...
