Noise is liable for generating troubles in day-to-day communication, so noise reduction is a
major issue. To acquire a signal free from distortion, the key objective is to terminate the …

Abstract Usually Acoustic Echo Cancellers (AECs) are realized by adaptive Finite duration
Impulse Response (FIR) filter having large number of coefficients and Least Mean Square …

The structure of an adaptive time varying linear filter largely depends on its tap-length and
the delay units connected to it. The no of taps is one of the most important structural …

The structural complexity and overall performance of the adaptive filter depend on its
structure. The number of taps is one of the most important structural parameters of the liner …

In recent times noise cancellation is a vital issue, as it is responsible for reducing undesired
disturbances in the process of communication. Active Noise Cancellation (ANC) is the most …

The problem of acoustic echo is well defined in case of hands-free communication. The
presence of large acoustic coupling between the loudspeaker and microphone would …

The priority of current era in noise cancellation field aims at blocking the low frequency noise
since most real life noises operate below 1 KHz. The noise which creates obstruction in …

An advanced low complexity, fast converging variable tap-length (VT) learning algorithm for
stereophonic acoustic echo cancellation (SAEC) based on multiple sub-filters (MSF) …

A low complexity Multiple Sub-Filters (MSF) parallel structure for monophonic acoustic echo
cancellation (AEC) has been proposed where order of each MSF has been estimated …

In this paper the order estimation of each sub-filter, in Multiple Sub-Filters (MSF), parallel
structure has been used for Stereophonic Acoustic Echo Cancellation (SAEC). The …
