检测技术中新的小波阈值函数的信号去噪

摘要

在信号检测技术中，构造了一个新的阈值函数，与传统的软硬阈值函数相比，连续性好，高阶可导，便于进行各种信号处理和检测。实验仿真结果表明，采用新的阈值函数的去噪效果在信噪比增益和均方误差意义上均优于传统的软硬阈值方法，给检测技术带来了新的发展。%In signal detection technology, and constructs a new threshold function, compared with the traditional soft and hard threshold function, has good continuity, high order derivative, is convenient for various signal processing and detection, simulation results show that, the denoising effect of the new threshold function of the SNR and both hard and soft threshold methods square error sense are superior to the traditional, brought the new development of detection technology.
