Research on Interference Filtering Technique for Power Communication under Ubiquitous Internet of Things
The scale of ubiquitous Internet of Things in power communication applications is much larger than that of ordinary Internet of Things,which leads to the interference of external devices that can affect the communication quality of power communication systems.To solve this problem,the interference filtering technique for power communication under ubiquitous Internet of Things is proposed.The reasons why the"Internet+"smart energy architecture and the ubiquitous Internet of Things architecture are more susceptible to interference are analyzed.By identifying the impulse interference information of the power communication collection signals under ubiquitous Internet of Things,the power communication impulse noise sparsity is obtained,and the power communication impulse noise interference estimation is calculated.The designed power communication interference filter is utilized to realize the power communication interference filtering under ubiquitous Internet of Things.From the results of power communication interference filtering test and bit error rate(BER)test under ubiquitous Internet of Things,the power communication original signal and noise addition signal waveforms have similarity and the similarity between the original signal and noise interference filtering results is high.The reliability of the technique is strong.
