In this paper, three new methods for two-dimensional (2-D) adaptive notch filter (ANF) are proposed. They not only contain similar and simpler structures but also can be derived by simpler adaptive algorithms compared with the previous ones. They are helpful for 2-D signal processing. Simulation results show that they can eliminate 2-D sinusoidal signals successfully.

Abstract Interference signals degrade global navigation satellite system (GNSS) performance and must be mitigated. Chirp can mitigated with an adaptive notch filter (ANF), but the dynamic behavior limits performance. An ANF determines instantaneous frequency removes interference a filter. However, there are several limitations. In this article, we propose multi-parameter (MPANF) approa...

Radio Frequency Interferences (RFI), such as strong Continuous Wave (CWI), can influence the Quality of Service (QoS) communications, increasing Bit Error Rate (BER) and decreasing Signal-to-Noise Ratio (SNR) in any wireless transmission, including a Digital Video Broadcasting (DVB-S2) receiver. Therefore, this paper presents an algorithm for detecting mitigating Multi-tone Interference (MCWI) ...

Attitude control of a flexible launch vehicle is addressed in this study. A ground experimental model is developed for verification of different stabilization strategies. The experimental set up duplicates planar motion of flexible launch vehicles as a coupled hybrid dynamics of rigid body pitching motion and flexible vibration. In particular, adaptive notch filter, which updates filter paramet...

The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...

the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...
