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 ...
متن کاملAdaptive 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...
متن کاملSubband Adaptive Filtering with Real–Valued Subband Signals for Acoustic Echo Cancellation
Adaptive filtering in subbands have originally been proposed to overcome limitations of classic adaptive algorithms in some areas. In general, subband adaptive filters offer computational savings, as well as faster convergence over the classical Least Mean Squared (LMS) algorithm. However, improvements to current subband adaptive filters could be further enhanced by a more elegant choice of the...
متن کاملAdaptive-Filtering-Based Algorithm for Impulsive Noise Cancellation from ECG Signal
Suppression of noise and artifacts is a necessary step in biomedical data processing. Adaptive filtering is known as useful method to overcome this problem. Among various contaminants, there are some situations such as electrical activities of muscles contribute to impulsive noise. This paper deals with modeling real-life muscle noise with α-stable probability distribution and adaptive filterin...
متن کاملNonlinear Adaptive Filtering for Echo Cancellation
This paper examines the problem o f nonlinear adaptive filtering for echo cancellation. The high speed requirements in digital subscriber loops and voiceband data modems place constraints on the design of adaptive echo cancellers due t o the presence o f nonlinearities. This paper considers table look-up structures and nonlinear filters based on the Volterra series for general nonlinearities, a...
