These drawbacks limit the turbo codes to the real time applications. In this paper, a parallel decoding with sliding window (PDSW) algorithm is proposed in order to reduce the memory requirement. On the one hand, the PDSW algorithm outperforms the serial algorithm by few tenths of a decibel with the same decoding complexity. In addition, it requires memory approximate one magnitude less than the serial algorithm. Hence this algorithm is valuable for the hardware implementation.","PeriodicalId":237858,"journal":{"name":"International Conference on Communication Technology Proceedings, 2003.

To achieve effective collaboration, the level of user behavior's simulation accuracy (LOA) in CVE must be high. But if we adopt static high LOA, system's scalability will be greatly decreased. So scalability request must compromise with collaborative request. This paper analyses CVE system's scalability request and collaborative request, and presents a classification of collaborative work and a definition of collaborative knowledge base (CKB). Based on CKB, a knowledge-based adaptive message filtering technique, which improves CVE system's scalability, is put forward.","PeriodicalId":237858,"journal":{"name":"International Conference on Communication Technology Proceedings, 2003.

In this paper, we proposed an inter-domain layered ION management system scheme dealing with the multi-domain network environment. And the management information models designed for ION are presented, especially that for the control plane and three connection types.
