Echo cancellation is one unavoidable module in any voice related communication systems such as telephone, mobile and VOIP. In several applications, run-time high speed echo cancellation can give better quality of service. Real-time echo cancellation is an important feature for hands-free operation of telecommunication equipment like mobile phones. A desirable acoustic echo control should be capable of handling double-talk as well. In this paper, the authors successfully implement a novel hardware architecture that is based on a robust adaptive algorithm in combination with a two path model to tackle the double-talk situation.
