Doppler and bearing tracking using fuzzy adaptive unscented Kalman filter
The topic of Doppler and Bearing Tracking (DBT) problem is to achieve a target trajectory using the Doppler and Bearing measurements. The difficulty of DBT problem comes from the nonlinearity terms exposed in the measurement equations. Several techniques were studied to deal with this topic, such as the unscented Kalman filter. Nevertheless, the performance of the filter depends directly on the...
متن کاملFuzzy Adaptive Variational Bayesian Unscented Kalman Filter
We consider the problem of nonlinear filtering under the circumstance of unknown covariance statistic of the measurement noise. A novel adaptive unscented Kalman filter (UKF) integrating variational Bayesian methods and fuzzy logic techniques is proposed in this paper. It is called fuzzy adaptive variational Bayesian UKF (FAVBUKF). Firstly, the sufficient statistics of the measurement noise var...
متن کاملCooperative Spectrum Estimation using Kalman Filter based Adaptive Bayesian System for Cognitive Radio
Efficient usage of a Cognitive Radio depends upon the fundamental aspect of Spectrum utilization. The Dynamic spectrum access belongs to spectrum holes estimation to utilize the natural resource in an effective way. Former works on spectrum approximation that predicted a perfect knowledge of the Signal to Noise Ratio of the received signal from the licensed users or primary users. In this paper...
متن کاملA Hybrid Adaptive Unscented Kalman Filter Algorithm
In order to overcome the limitation of the traditional adaptive Unscented Kalman Filtering (UKF) algorithm in noise covariance estimation for statement and measurement, we propose a hybrid adaptive UKF algorithm based on combining Maximum a posteriori (MAP) criterion and Maximum likelihood (ML) criterion, in this paper. First, to prevent the actual noise covariance deviating from the true value...
متن کاملWideband Spectrum Sensing Using Adaptive Neuro Fuzzy Inference System in Cognitive Radio Networks
Radio Frequency (RF) spectrum is anexpensive and limited natural resource for wireless communication systems. In recent times, Cognitive Radio (CR)has come out as one of the most competent candidates for enhancing the spectral exploitation effectiveness. Spectrum sensing is one of the most decisive elements in a CR system facilitating CR to access the licensed spectrum when it is not exploited ...
