| Abstract: | 3G wireless transmission is a new type of real-time multimedia transmission method,and is more flexible and convenient compared to the conventional methods.To overcome the data packet loss in 3G wireless network,this paper introduced the method of using FEC and interleaving to increase the data correctness in the transfer,and mainly researched on the design and realization of interleaving and RS(204,188) code.In the end,the test results of the whole system are given under different channels that have various packet loss rates. |
