射频通信信号传输精度优化处理仿真研究

Simulation Study on Optimization of Transmission Accuracy of Radio Frequency Communication Signal

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。

An optimization method for transmission accuracy of radio frequency （RF） communication signal is proposed based on smoothness priori theory. Firstly, integrated with the smoothness priori theory, an observation mod- el of RF communication signal is built. Then,trend item of original RF communication signal is estimated and inte- grated with frequency domain of the trend item in the communication signal, and value of normalizing parameter is ob- tained. Moreover,hierarchical processing is carried out for signal with eliminating trend item by using multi -resolu- tion analysis and wavelet filter is carried out for the RF communication signal. Finally, the optimization of transmis- sion accuracy is completed. Simulation results show that the proposed method can improve the transmission accuracy effectively.
