摘要
采用智能天线技术可提高物联网的系统容量以及无线通信系统的频谱利用率。通过建立阵列幅相误差模型,针对ESB算法进行稳健性分析,探讨阵列幅相误差情况对算法性能的影响,并给出MATLAB仿真分析图。实验结果表明,阵列幅相误差会使得实际阵列方向矢量不再是理想条件下的阵列方向矢量,进而严重影响了智能天线系统的性能。
The system capacity of IOT and spectrum utilization of wireless communication systems can be improved by smart antenna technology. Array amplitude and phase error model is established in this paper and then robustness analysis of ESB algorithm is given to explore the effect of array amplitude and phase error on algorithm performance. Also the analysis by MATLAB simulation is given. Experimental results show that array amplitude and phase error does not make the actual array direction vector under ideal conditions any longer, which will seriously affect the performance of smart antenna system.
