摘要 适用于有线网络的传统独立分层协议阻碍和限制了未来IMT-Advanced无线网络性能进一步提升,无线网络的发展需要新的优化技术与之相适应。高效跨层、跨模块的资源优化技术,通过发掘各层次、各模块之间的冗余信息,或压缩,或利用,能够明显地改善无线系统性能。跨层优化技术在结合认知科学技术、人工智能技术、凸优化等数学手段的基础上,能对各模块资源合理优化分配,最大程度地提高无线系统的资源利用效率,为网络内无线节点提供更好的业务服务质量(QoS)保障以及用户体验。 To develop IMT-Advanced wireless networks, new optimization technology is required. The traditional independent layer protocol limits performance and will hamper the improvement of future IMT wireless networks. Efficient cross-layer cross-module optimization technology significantly improves wireless system performance by compressing or using the redundant information across all levels and modules. Cross-layer optimization combines cognitive science, artificial intelligence, and convex optimization to efficiently allocate and use resources, and to optimize each module. QoS and user experience is also guaranteed.
