本文介绍了未来第四代移动通信系统中可能的联合编码框架，在分析基于小波变换的SPIHT算法和LDPC编码算法的基础上，添加了高斯白噪声后给出了一种改进的无线传输系统结构。仿真结果表明，这种利用信源特性进行信道编译码的方法能够有效地传输信息，提高信道编码的交错性能，这种改进方案能更好地适合于未来多媒体无线传输业务的需求。

This article introduced in future fourth generation of mobile communication system possible union code frame, in the analysis based on the wavelet transformation's SPIHT algorithm and in the LDPC encoding algorithm's foundation, after increasing the white gaussian noise, has given one kind of improvement wireless transmission system structure. The simulation result indicated that this kind carries on the channel using the source characteristic to arrange the decoding the method to be able to transmit the information effectively, enhances the channel coding the staggered performance, this kind of improvement program can suit well in the future multimedia wireless transmission service demand.
