An exhaustive review of adaptive signal processing schemes which are robust, sparsity-
aware and robust as well as sparsity-aware has been carried out in this paper. Conventional …

In this paper, a variable threshold voice activity detector (VAD) is developed to control the
operation of a two-sensor adaptive noise canceller (ANC). The VAD prohibits the reference …

Noise cancellation systems are useful in applications such as speech and speaker
recognition systems where the effects of environmental noise have to be taken into …

At the end of communication system information signal may be introduced with some noise
along with the information signal. Noise may be additive or convoluted. Adaptive filter finds …

With the tremendous growth in the Digital Signal processing technology, there are many
techniques available to remove noise from the speech signals which is used in the speech …
