Description: The (a) section of Figure 1 illustrates the Line Echo Canceller (LEC) residing in the access network where echoes occur. Other voice processing modules, such as Automatic Level Control (ALC) and Noise Reduction (NR), are shown merely for illustration purposes. On the terminal side, both acoustic and electrical echo can occur. If the voice terminal is a speaker telephone set with an open acoustical path from the speaker to the microphone, the effect of acoustical echo is combined with the effect of the network echo. Because there is only a miniscule delay between the electrical signal and its echo, the speaker/listener is exposed to an effect known as side tone. Typically, instead of mounting a LEC at the terminal, side tone circuitry is placed to control the amount of the returned energy. The (b) section of Figure 1 shows examples of echo canceller signals representing the following: Platform: |

Description: The problem of noise reduction has attracted a
considerable amount of research attention over the past several
decades. Among the numerous techniques that were developed,
the optimal Wiener filter can be considered as one of the most
fundamental noise reduction approaches, which has been de-lineated in different forms and adopted in various applications.
Although it is not a secret that the Wiener filter may cause some
detrimental effects to the speech signal (appreciable or even sig-nificant degradation in quality or intelligibility-SINCE we are living in a natural environment where noise
is inevitable and ubiquitous, speech signals are gener-ally immersed in acoustic ambient noise and can seldom be
recorded in pure form. Therefore, it is essential for speech
processing and communication systems to apply effective nois Platform: |

Description: Adaptive filtering constitutes one of the core technologies in digital signal processing and finds numerous application areas in science as well as in dustry. Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beamforming. Acoustic echo cancellation is a common occurrence in today’s telecommunication systems. The signal interference caused by acoustic echo is distracting to users and causes a reduction in the quality of the communication. This paper focuses on the use of LMS and NLMS algorithms to reduce this unwanted echo, thus increasing communication quality. -Adaptive filtering constitutes one of the core technologies in digital signal processing and finds numerous application areas in science as well as in industry.
