Abstract: Echo phenomenon is a common problem in voice communication system,which affects the communication quality.This paper presented an echo cancellation algorithm based on WebRTC (Web Real-Time Communication).As the fixed-point realization is limited,the algorithm uses floating-point computation to improve algorithm efficiency and accuracy,while maintains algorithm speed.The experimental results based on mobile equipments show that the proposed algorithm outperforms the original one on echo return loss enhancement with comparable complexity.
