Problems solved by technology

If the time domain amplitude is too high, it will cause frequency domain signal saturation, and for high-order modulation (such as 16QM, 64QAM), it will directly lead to demodulation and decoding failure
Therefore, this method is d

Abstract

The invention provides a pulse interference suppression method and device, equipment and a storage medium. The pulse interference suppression method comprises the following steps: S1, acquiring communication data; s2, control parameters of the communication data are calculated, and the control parameters comprise average power and position parameters; s3, performing gain judgment and sample point number estimation according to the control parameters; and S4, if the gain judgment result is yes, performing analog AGC gain adjustment on the communication data according to the difference value between the average power and the saturation target gain, and performing digital DGC gain adjustment on the signal after analog AGC gain adjustment according to the sampling point number estimated by the sampling point number so as to suppress the pulse interference signal. One technical effect of the embodiment of the invention is that the design is reasonable, the rapid saturation of pulse interference can be realized, the signal is prevented from being saturated, and the purpose of pulse suppression is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power communication, and in particular relates to a pulse interference suppression method, device, equipment and storage medium of an OFDM-based PLC system. Background technique [0002] In the field of power communication, power line carrier communication solutions based on OFDM (Orthogonal Frequency Division Multiplexing, namely Orthogonal Frequency Division Multiplexing) are proposed, such as G3-PLC, Green-PHY and Broadband Power Line Carrier (BPLC) . The power line carrier communication technology can directly use the existing power line for data transmission without rewiring, the networking is simple and fast, the cost is low, the application range is wide, and the information security is guaranteed. The OFDM-based PLC communication technology is widely used in smart grid meter reading systems, energy Internet, smart home, industrial data collection and other scenarios. OFDM-based PLC comm...
