This paper investigates the autocalibration of microelectromechanical systems (MEMS) triaxial accelerometer (TA) based on experimental design (DoE). First, for a special 6-parameter second-degree model, a six-point experimental scheme is proposed, and its G-optimality has been proven based on optimal DoE. Then, a new linearization approach is introduced, by which the TA model for autocalibration can...
In order to diagnose the II Ill-conditioning of the parameter estimation system in the modern surveying and mapping data processing, the effectiveness of observation is analyzed using observation structure. Through the QR decomposition of observation matrix, we transfer the analysis of the observation structure into the analysis of R matrix, then we propose a relative-volume method to analysize the...
An algorithm to detect and estimate frequency hopping signal corrupted by white Gaussian noise is presented. The proposed algorithm is based on atomic decomposition and information theoretic criterion. The stopping criteria of atomic decomposition is supplied by modified information criterion. Detection and parameter estimation are performed after atomic decomposition. Numerical experiments have shown...
The parameter estimation of frequency hopping signals under non-cooperative conditions is a key problem to which more attentions are being paid in the field of signal processing. According to the structure of frequency hopping signals, three-parameter time-frequency atoms were obtained from Gabor functions by successive applications of scaling, time-shift and frequency-shift operators, and a new atomic...
