论文摘要
本文介绍了一项最近进行的室内到室外测量活动，用于调查基于$ 8 $的$ 8 \ times 8 $虚拟多输入 - 摩尔特式（MIMO）无线传感器网络（WSN）的传播特征。该活动是在没有窗户的仪表室里进行的，但充满了不同的嘈杂的电气和测量单元。当20 MHz宽的信号以2.53 GHz传输时，通道脉冲响应将报道。收集了15种不同空间组合的测量。在分析了收集的数据后，计算每个测量场景的系统容量和可实现的传输速率。使用这些值，我们检查了定位可以最大化整体网络吞吐量的传感器的最佳配置。结果表明，在房间的所有4个墙壁上分发传感器可以达到最高的信息率。
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.
