A fault-tolerant recognition method for services packets based on center distance and BP net

In view of the appearance of error bits in the process of data transmission, the individual erroneous bit of real-time services do not affect the use of services packets. The fault-tolerant type recognition of real-time packet is the first problem in the process of restructuring. In this paper, a non-linear recognition method which combined “center distance” and BP net together is proposed and applied to factual data for erroneous packets, The results show that the method proposed performs much better than the regular method.
