Problems solved by technology

The traditional front-end equipment instrument system is composed of the front-end primary instrument, the back-end secondary instrument and the transmission line between them. The analog / digital converter (ADC: Analog to Digital Converter) is usually arranged in the back-end secondary instrument. Therefore, The useful signal on the transmission line is a highly sensitive analog signal, which is extremely vulnerable to electromagnetic interference and reduces the reliability of the equipment

Abstract

The invention discloses a front-end digitallizer based on an FPGA. The front-end digitallizer comprises a digital front end and an analytical back end, wherein the digital front end is connected to the analytical back end; the digital front end is used for collection, pre-processing, storage and transmission of a spatial electromagnetic signal, packaging an original spatial electromagnetic signal and feature value data into a data frame and transmitting the data frame to the analytical back end; and the analytical back end is used for receiving and analyzing the data frame sent by the digital front end, carrying out data post-processing on the data frame and providing interface management. The device has strong electromagnetic compatibility, and measurement capability of characteristic parameters of the spatial electromagnetic signal of heavy sensitive equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an FPGA-based front-end digital device. Background technique [0002] In the military field, "complex electromagnetic environment" is usually used to describe objectively existing complex electromagnetic phenomena, and the electromagnetic compatibility of information equipment is used to characterize the anti-interference ability and robustness of equipment; in the industrial field, with the modern communication and power electronics The rapid development of technology and the large-scale application of high-power nonlinear equipment produce power harmonics that pollute the power grid and radiate electromagnetic waves to the surroundings. Therefore, the electromagnetic environment of industrial measurement and control sites is becoming increasingly complex. However, electronic system equipment such as satellite communication, mobile communication, and electronic co...
