Abstract

The invention discloses an emission detection circuit based on analog-to-digital signal processing of a transmit-receive assembly. The emission detection circuit is provided with a signal processing device, an FPGA logic control circuit, a DAC module, an ADC module, a radio frequency emission channel, a radio frequency reception channel, a transmit-receive change-over switch and a transmit-receiveantenna. On the basis of the radio frequency channel, the signal processing device used for detection control, the DAC module used for radio frequency emission, the ADC module used for detection marksignal return and the FPGA logic control circuit used for detection result judgment output are arranged, the technical problem that in the prior art, the judgment precision of successful transmissionof signals on a receiving and transmitting assembly is not high is solved.

Description

technical field [0001] The invention relates to the communication field, in particular to a transmission detection circuit based on analog-digital signal processing of a transceiver component. Background technique [0002] When the transceiver component is performing normal transmission operations, it needs to know whether the signal is actually transmitted. The detection (amplitude demodulation) is the inverse process of the amplitude modulation. Through the detection operation, it is possible to know whether the signal is transmitted through the antenna. [0003] At present, the circuits that realize the detection are all analog circuits, and the detection circuit is mainly composed of three parts, namely: a high-frequency modulated signal source, a nonlinear device, and an RC low-pass filter. The output of this kind of detector will depend on the amplitude of the signal (there is no definite threshold), and when the transceiver component transmits normally, the amplitude ...
