The invention discloses an emission detection circuit based on transmit-receive assembly detection mark signal processing. A detection control terminal, an emission signal source, an FPGA logic control circuit, a DAC module and a radio frequency channel are arranged; the detection control terminal is used for providing an emission detection control signal for the FPGA logic control circuit and theradio frequency channel, and the emission signal source is used for providing an emission detection signal source for the FPGA logic control circuit and the DAC module; then, the radio frequency channel detects and outputs the emission signal according to the received emission detection control signal, and feeds back a detection mark signal to the FPGA logic control circuit during radio frequencyoutput; and finally, the FPGA logic control circuit is used for outputting a detection result according to the received transmitting detection control signal, the signal source and the detection marksignal. On the basis of the radio frequency channel, the detection control device, the DAC module and the FPGA logic control circuit are arranged, the technical problem that in the prior art, the judgment precision of successful transmission of signals on a receiving and transmitting assembly is not high is solved.
Description
technical field [0001] The invention relates to the field of communication, in particular to a transmission detection circuit based on signal processing of a detection signal 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 ...
