Abstract :
The packet-level Reed-Solomon (PRS) code can help to recover burst loss packets for VoIP service over wireless networks. A detailed study on PRS code over a burst loss channel is carried out by means of simulation in this paper. The Gilbert model based on a two-state Markov chain is established for the burst-loss channel. The encoding and decoding algorithms of the PRScode including the truncated code are given. The performance of different PRS codes with three burst-loss channel parameters is obtainedand the relationship between the improved performance and the PRS codes over burst-loss channels is discussed. Based on our study, a method of choosing the suitable PRS codes over burst-loss channel is advised at the end of the paper.
