The Design and Implementation of Digital Repeater with Echo Canceller in Mobile Multimedia Network

摘要：

In mobile multimedia network, the digital repeater with echo cancellation is the key equipment. In order to keep the repeater stable, the echo canceller is used to reduce the impact of the unwanted echoes. This paper proposes one method to implement echo cancellation in multimedia network, and gives the hardware implementing solution. Furthermore, we design the digital repeater with echo canceller according to the method. Verified by simulation and actual repeater, the proposed method is a very good way to implement echo cancellation for digital repeater. The echo cancellation algorithm is reliable and hardware cost is low. The method can greatly increase output power of digtal repeater.
