Asymptotic Data Rates of Receive-Diversity Systems with MMSE Estimation and Spatially Correlated Interferers

Siddhartan Govindasamy

摘要:

提出了一种渐近技术来表征在空间分布式网络中具有相关位置处的有源中继器、N个接收分集分支和线性最小均方误差(MMSE)接收器的代表性无线链路上可实现的比特/符号。这个框架,然后应用到系统,包括类似物的Matern I型和II型网络,这是有用的模型系统与媒体访问控制(MAC),蜂窝上行链路与正交传输和频率复用,和布尔集群网络。据发现,对于我们的网络模型,与适度大的N,的相关性之间的位置并不显着影响的比特/符号,导致在简单的近似值的数据率可实现在这样的网络,这是已知的是难以分析,并为其中很少的分析结果是可用的。

英文摘要:

An asymptotic technique is presented to characterize the bits/symbol achievable on a representative wireless link in a spatially distributed network with active interferers at correlated positions, N receive diversity branches, and linear Minimum-Mean-Square-Error (MMSE) receivers. This framework is then applied to systems including analogs to Matern type I and type II networks which are useful to model systems with Medium-Access Control (MAC), cellular uplinks with orthogonal transmissions and frequency reuse, and Boolean cluster networks. It is found that for our network models, with moderately large N, the correlation between interferer positions does not significantly influence the bits/symbol resulting in simple approximations for the data rates achievable in such networks which are known to be difficult to analyze and for which few analytical results are available.
