中文摘要: 在目前移动数据流量呈爆炸性增长的背景下,现有的蜂窝网络已无法负担庞大的数据需求,而高速、经济的无线局域网络恰恰有效地弥补了蜂窝网络的不足,成为分流大数据流量的最有效途径。然而当前盛行的网络协议并不能有效地提高无线信道的利用率,其根本原因在于他们不能提供高效低耗的信道信息。 针对信道利用率低的问题,本项目将设计一个新的附加传输技术,通过附加传输技术,以提供高效准确的信道信息,并最终提高无线网络的整体性能。我们首先研究附加传输技术的基础理论与实现,在此基础上研究基于附加传输的快速信道接入策略和多信道分配策略。最后基于以上协议我们将搭建附加传输的系统和测试平台,并利用实际节点进行实验,验证整个附加传输设计在真实的无线通信信道中的各种性能参数。

英文摘要: Due to the rapid progress of mobile data traffic, current cellular network cannot support the mass data. In this case, the wireless local area network (WLAN) can support such data as its high speed and free properties. However, the popular MAC protocol cannot improve the channel ultilization effectively. The fudamental problem is that they cannot provide the channel information in low cost and high effective manner. In order to solve this low channel ultilization problem, we design a new physical layer technique called attachment transmission. We can provide the accurate and effective channel information by using attachment transmission. Therefore, we can enhance the wireless network performance. We first investigate the basic theory of the attachment transmission technique. And then we will propose the current transmission scheme based on this novel technique to design a fast channel access algorithm and channel allocation algorithm. Finally, we will implement this technique and its related applications on the software radio platform to test its performance.
