Research on Optimizing the Carrier-to-Noise Ratio of RDSS Inbound Signal Based on Improved Moving Weighted Average Method

The measurement and control center has the problem that the estimation of the inbound signal Carrier-to-Noise Ratio (CNR) of RDSS users is relatively rough. A method for optimizing the CNR of the user's inbound signal based on an improved moving weighted average method is proposed to solve the problem. Firstly, analyze and preprocess the characteristics of the inbound CNR of RDSS users. Then build an improved weighted moving average method model according to user characteristics. Finally, the actual engineering data is used to compare the improved moving weighted average method and the average method. The sliding parameters in the improved moving weighted average method are optimized to verify the feasibility and accuracy of the method. Experimental results show that the enhanced moving weighted average method is better than the average, and when the sliding parameter is 5, the effect of this method is better.
