【摘要】：对射频通信信号传输精度进行优化,可以有效削弱射频通信非平稳信号的影响。对通信信号传输精度的优化,需要对信号进行分层处理,然后对信号进行小波滤波,完成对通信信号传输精度的优化。传统方法组建信号尖端点的隶属度函数,得到各个信号点的尖端程度,但忽略了对信号进行小波滤波,导致传输精度优化效果不理想提出基于平滑先验的射频通信信号传输精度优化方法。结合平滑先验理论组建射频通信信号观测模型,估计原射频通信信号中的趋势项,并结合射频通信信号中趋势项的频率范围,得出标准化参数取值,利用多分辨率分析对消除趋势项的信号进行分层处理,对射频通信信号进行小波滤波,以此为依据完成对射频通信信号传输精度优化。实验结果表明,所提方法能够有效提高射频通信信号传输精度。
[Abstract]:By optimizing the transmission accuracy of RF communication signal, the influence of non-stationary signal of RF communication can be effectively reduced. In order to optimize the transmission accuracy of communication signal, it is necessary to process the signal in layers, and then wavelet filter is used to optimize the transmission accuracy of communication signal. In the traditional method, the membership function of the signal tip point is constructed, and the tipping degree of each signal point is obtained, but the wavelet filtering of the signal is neglected. As a result, the transmission accuracy optimization method based on smoothing a priori is proposed. Based on the smoothing priori theory, a radio frequency signal observation model is established to estimate the trend term in the original radio frequency communication signal and the frequency range of the trend term in the radio frequency communication signal. The multi-resolution analysis is used to process the signal which eliminates the trend term and wavelet filter is used to optimize the transmission precision of the radio frequency communication signal. Experimental results show that the proposed method can effectively improve the accuracy of RF communication signal transmission.
