A Scheme for Jitter Elimination in IP Real-Time Service

With the development of wireless communication technology, more and more conversation is based on IP protocol, the time-delay jitter is unavoidable in IP conversation due to it provide a best-effort service. In this paper, a scheme uses jitter buffer to eliminate jitter is proposed, the adaptive jitter buffer is set to solve the jitter problem and control the packet loss rate. In the meantime, LMS (Least Mean Square) algorithm is used to adjust the length of buffer by predicting the average jitter in next period. To prove the performance of the scheme, time-delay and packet loss rate are simulated on OPENT. Compared with the existing method, the scheme is proved that it can provide lower packet loss rate and smaller jitter.
