Digital simulation for the integrated imformation transmission network of a certain power company is performed, the QoS under three configuration schemes, i.e., without QoS configuraiton, with simple differnece service configuraiton and with MPLS network configuration, are compared. Comparison resutls show that the configuration scheme of MPLS network can implement the load balance among link circuits and possesses fault self-recovery mechanism, so the failure elements can be quickly detected and the switching over of data flow among label switched paths can be realized. The fault recovery time is within miliseconds, therefore the QoS of power system realtime information can be ensured effectively and the QoS of various non-realtime information can be considered as well.

To extend the SIC technique to turbo-coded systems, an iterative IC with ordered SIC at front-end is proposed. To avoid unnecessary computation, the ordering information obtained from SIC front-end is utilized in a low-complexity stopping criterion with high efficiency. In addition to bit-wise interference cancellation, the SIC technique is also applied to code-block-wise interference cancellation. And, only the bits in incorrect blocks should be preceded to the next outer iteration. As a result, huge amount of computational complexity can be saved, and better performance is achieved.

最后，我们延伸序列式干扰消除的概念至有通道编码的系统，与涡轮码解码同时考虑，首先根据排序资讯，提出一提早停止（early-stopping）准则以减少涡轮码解码时不必要的运算，与其他提早停止准则比较，在几乎相同的检测能力下，此准则具有快速及低计算复杂度的特性，接著提出一包含前述准则之递回式干扰消除法，将序列式干扰消除运用在符码及跨级之码块干扰上，并且只有被检定为错误的编码区块讯号需要再进一级的递回检测，此法不仅在效能表现上更为优越，也节省了大量且不必要的计算量。
