针对航空无线通信对信道估计的需求，设计了一种适用于航空无线信道的信噪比估计器，其采用分段方法在Simulink仿真中实现精确拟合，同时提出在FPGA中进行矩分析，并采用查表的方法输出信噪比估值。实验表明，该方法较传统方法具有高实时性和低复杂度的特点，满足航空无线通信的技术要求。%This paper presents a SNR estimation method to satisfy the need of channel estimation for Aviation Wireless Communication. It shows a precise fitting effect in simulation based on section division, and promotes the SNR calculation architecture by Moment Analysis and LUT in FPGA. Experiences show that this method has the higher real-time performance and lower complexity to fit the requirements for Aviation Wireless Communication.
