Abstract
In order to deeply analyze the performance of Electromagnetic Field (EMF) on wireless sensor Signal Processing (SP), this paper first examines the influencing factors of wireless sensor SP performance based on the relevant theories of EMF and wireless sensor. Then, it discusses the influence of EMF on wireless sensor information Transmission and Reception (T & R) time, Package Reception Rate (PRR), and communication throughput. Furthermore, the Packet Loss Rate (PLR) and Bit Error Rate (BER) of the sensor are described, and finally, a conclusion is drawn. The research findings are as follows. This paper makes a statistical study on whether the wireless sensor is disturbed by EMI from three aspects (wireless sensor’s information T & R time, PLR, and communication throughput). In any case, EMF will prolong the wireless sensor’s information T & R time and reduce the PRR and communication throughput. When the distance between the transmitter and the receiver is set to 5 m, the change of field intensity at the transmitter significantly impacts the BER but has little impact on the PLR. However, when the field intensity of the transmitter and the receiver is the same, PLR and BER show no evident difference. Therefore, this paper studies the SP performance of the wireless sensor in the EMI environment, which provides an excellent reference significance for the rapid development of wireless sensors in the future.

Summary
With Science and Technology (S & T) advancement, Wireless Sensor Technology (WST) is seeing a more important role in production and life. Abdel et al proposed to analyze the EMF influence on wireless sensors’ SP performance by a boundary element method. Li et al optimized the strategy of Abdel et al and introduced multicircuit and multisplit transmission lines instead of the single-circuit transmission line and discovered that the ground EMF Intensity (INT) would increase with the increase of the number of split transmission lines and the distance between the EMF [7] In this context, the present work starts with the wireless sensors’ SP performance expounds on the influence of EMF on wireless sensors from information Transmission and Reception time, information reception rate, and communication throughput. According to a particular theoretical logical order, the present work comprehensively analyzes the research on wireless sensor SP performance in an EMI environment using comparative analysis and other methods.
