Abstract :
Hands-free operation of telephones, incorporating echo cancellation and noise reduction, has been discussed for over a decade. This paper presents an overview of the wide range of algorithms which are applicable to echo cancellers and noise reduction. Practical problems associated with implementation and overall system control are also discussed.
