Vibration Suppression of Fuel Sloshing using Subband Adaptive Filtering (RESEARCH NOTE)

Acoustic Echo Cancellation Using Subband Adaptive Filtering

Adaptive ltering has been successfully used in canceling line echos in the telephone network since the 1960's [179, 443, 387]. In these cases, the adaptive lter is used to model the unknown echo path in a communications channel and then cancel the echo signals from the conversation. An adaptive lter is required because the echo path is not only unknown, but also because it is di erent for each ...

Adaptive Filtering Using Subband Processing: Application to Background Noise Cancellation

Adaptive filters are often involved in many applications, such as system identification, channel estimation, echo and noise cancellation in telecommunication systems. In this context, the Least Mean Square (LMS) algorithm is used to adapt a Finite Impulse Response (FIR) filter with a relatively low computation complexity and good performance. However, this solution suffers from significantly de...

A new approach to subband adaptive filtering

Subband adaptive filtering has attracted much attention lately. In this paper, we propose a new structure and a new formulation for adapting the filter coefficients. This structure is based on polyphase decomposition of the filter to be adapted and is independent of the type of filter banks used in the subband decomposition. The new formulation yields improved convergence rate when LMS algorith...

Design of Random Vibration Controller using Adaptive Filtering

In this paper a control scheme for electro-dynamic shaker control is proposed. The proposed controller is best suitable for random vibration control in which the excitation signal is a random signal. The controller designed is using acceleration power spectral densities and adaptive filtering technique. The proposed scheme eliminates the requirement of tracking filters in the vibration control ...
