摘要:

本文对室内无线传播环境下的单输入多输出(SIMO)信道进行了实验研究。在2.4 GHz的ISM频段的室内信道测量已经使用一个多功能的信道探测器测试平台进行。使用单个发射天线、具有两种拟议几何形状的四个接收天线和四分支接收器电路,以便利用基带信号处理技术实现信道探测器测量。通过信号强度、增益系数和容量三种度量指标对SIMO无线信道性能进行了深入研究。性能结果表明SIMO信道容量增强,并说明了两个建议的几何形状之间的差异。

英文摘要:

This work presents an experimental study of Single Input Multiple Output (SIMO) channel performance in indoor radio propagation environment. Indoor channel measurements at 2.4 GHz ISM frequency band have been performed using a versatile channel sounder testbed platform. A single transmitting antenna, four receiving antennas with two proposed geometries and a four-branch receiver circuitry were used in order to achieve channel sounder measurements exploiting baseband signal processing techniques. Deep investigation on SIMO wireless channel performance was realized through three types of metrics which are signal strength, gain coefficient and capacity. Performance results indicate SIMO channel capacity enhancement and illustrate differences between the two proposed geometries.
