无线网络中的邻居发现:一种多用户检测方法

Neighbor Discovery in Wireless Networks:A Multiuser-Detection Approach

Daniele Angelosante, Ezio Biglieri, Marco Lops

摘要:

我们研究的问题,确定哪些节点是邻居的一个给定的无线网络。我们考虑一个无监督的网络工作在频率平坦的高斯信道,其中$K+1$节点将其身份与非正交签名相关联,在随机时间,同步和独立地传输。介绍和分析了一些基于不同优化准则的邻居发现算法。数值结果表明,如何降低复杂度的算法可以达到令人满意的性能。

英文摘要:

We examine the problem of determining which nodes are neighbors of a given one in a wireless network. We consider an unsupervised network operating on a frequency-flat Gaussian channel, where $K+1$ nodes associate their identities to nonorthogonal signatures, transmitted at random times, synchronously, and independently. A number of neighbor-discovery algorithms, based on different optimization criteria, are introduced and analyzed. Numerical results show how reduced-complexity algorithms can achieve a satisfactory performance.
