Low-Power Communication Signal Enhancement Method of Internet of Things Based on Nonlocal Mean Denoising

In order to improve the transmission effect of low-power communication signal Internet Things and compress enhancement time signal, this paper designs a method based on nonlocal mean denoising. Firstly, residual one-dimensional layer is preprocessed by convolution core obtain layer. Then, according two classification recognition methods, noise reduction feature realized, algorithm used remove Things, weight value between similar blocks calculated European distance method. Finally, realized denoising The experimental results show that overhead low, which always less than 2.6 s. lowest bit error rate after about 1%, signal-to-noise ratio up 18 dB, shows can achieve enhancement.
