摘要
目前,射频EAS系统的市场应用仍十分广泛,伴随着日益严重的电磁干扰,其抗干扰性能面临着更大的挑战。此文针对一体式射频EAS系统如何提高其抗干扰性能进行研究。根据不同干扰噪声的特点,对稳态干扰和瞬时干扰在系统工作的各个环节上的影响进行分析,有针对性地给出了一系列包括硬件和软件等方面的方法,提出了一种以信噪比为基础提高系统自适应能力的算法,并结合实验仿真进行了验证,结果表明,本方法提升了系统的抗干扰能力和稳定性。
At present, the market of RF-EAS systems is still very large, accompanied by an increasingly serious electromagnetic interference the anti-jamming performance of it also faces greater challenges. This thesis takes AIO （All-In-One） type of RF-EAS systems as the object to study how to improve its anti-interference performance. Interference noise in the article is divided into two types, which are steady noise and transient noise. According to the characteristics of different interference noises, their impacts on all aspects of the system are fully analyzed, and then, we propose a series of targeted hardware and software measures. Finally, the self-adaptability of the system is studied, and we present a feasible way to improve the anti-interference ability and stability of the system.
