虚拟MIMO无线传感器网络在实测MIMO信道上的吞吐量分析

Throughput Analysis for Virtual MIMO WSNs over Measured MIMO Channels

摘要:

本文介绍了最近进行的一项室内到室外测量活动,以研究基于$8 \times 8$虚拟多输入多输出(MIMO)的无线传感器网络(WSN)的传播特性。该活动在没有窗户的仪器室中进行,但充满了不同的嘈杂的电气和测量单元。当以2.53 GHz发射20 MHz宽的信号时,报告信道冲激响应。测量收集15个不同的空间组合的发射天线。在分析所收集的数据之后,针对每个测量场景计算系统容量和可实现的传输速率。使用这些值,我们检查了定位传感器的最佳配置,可以最大限度地提高整体网络吞吐量。结果表明,将传感器分布在房间的所有4面墙上可以实现最高的信息速率。

英文摘要:

A recently conducted indoor-to-outdoor measurement campaign for investigating the propagation characteristics of an $8 \times 8$ virtual multiple-input-multiple-output (MIMO) based wireless sensor network (WSN) is presented in this paper. The campaign is conducted in an instrumentation room devoid of windows, but filled with different noisy electrical and measuring units. The channel impulse responses are reported when a 20 MHz wide signal is transmitted at 2.53 GHz. Measurements are collected for 15 different spatial combinations of the transmit antennas. After analyzing the collected data, system capacity and achievable transmission rates are calculated for each measurement scenario. Using these values, we examined the best configuration for positioning the sensors that can maximize overall network throughput. Results demonstrated that distributing sensors on all 4 walls of the room can achieve the highest possible information rate.
