摘要
广义Turbo乘积码(GTPC)可以把不同的信源混合在一起以不同的方式编码。介绍一种多级GTPC的结构,该结构对于不同的信源,可根据各自的需求,选取不同的码型进行编码,然后组成GTPC数据帧。并提出一种在异步传输模式(ATM)应用多级GTPC的组帧方式,理论和仿真结果表明,该方式能在多业务混合编码的情况下提升通信系统的性能以及节省带宽。
GTPC(Generalized Turbo Product Code) can combine different information source with different code. This paper introduced a multilevel GTPC structure. According to the requirement of each information source, this structure can choose different code type and construct a GTPC frame. This paper discussed the way of GTPC frame construction in ATM(Asynchronous Transfer Mode). Theory and simulation result shows that the performance of communication system can be upgraded and the bandwidth resource can be saved under this frame construction in multi-operation mixed code service.
