Optimal multistage Kalman estimators
نویسندگان
چکیده
An optimal multistage Kalman estimator (OMSKE) is proposed as a generalization of the optimal two-stage Kalman estimator for the reduction of the computational burden of the Kalman estimator (KE) for discrete-time linear time-varying systems with triangular transition matrices. This new filter is obtained by applying a multistage transformation to decouple the covariances of the KE. It is shown analytically that the computational complexity of the OMSKE is less than that of the KE and is minimum when the system transition matrix has the maximum stage number.

Self-tuning Information Fusion Kalman Filter for Multisensor Multi-channel ARMA Signals with Colored Measurement Noises and its Convergence
For the multisensor multi-channel autoregressive moving average (ARMA) signals with white measurement noises and an ARMA colored measurement noise as a common disturbance noise, a multi-stage information fusion identification method is presented when model parameters and noise variances are partially unknown. The local estimators of model parameters and noise variances are obtained by the multi...
متن کاملA moving fixed-interval filter/smoother for estimation of vehicle position using odometer and map-matched GPS
This paper presents some optimal real-time and post-processing estimators of vehicle position using odometer and map-matched GPS measurements. These estimators were based on a simple statistical error model of the odometer and the GPS which makes the model generalizable to other applications. Firstly, an asymptotically minimum variance unbiased estimator and two optimal moving fixed interval fi...
متن کاملKalman filtering for power estimation in mobile communications
In wireless cellular communications, accurate local mean (shadow) power estimation performed at a mobile station is important for use in power control, handoff, and adaptive transmission. Window-based weighted sample average shadow power estimators are commonly used due to their simplicity. In practice, the performance of these estimators degrades severely when the window size deviates beyond a...
متن کاملOptimal and suboptimal separate-bias Kalman estimators for a stochastic bias
This paper addresses two issues concerning the separate-bias Kalman estimator. The first of these issues deals with the derivation of the optimal estimator for the general case in which the bias vector is stochastic in nature, and the second issue deals with defining a suitable suboptimal realization of the generalized estimator.
متن کاملTeng Joon Lim 8 Form 101 – Application for a Grant Part Ii 1 Recent Progress in Research 1.1 Multiuser Receiver Design
The joint detection of multiple signal streams, usually transmitted using code division multiple access (CDMA), can give much better performance than conventional matched-filter methods. Receivers designed using this idea are generically known as multiuser detectors. Our work in this area has included the development of a recursive chip-rate detector that gives linear minimum mean squared error...
