1results about How to "Improve signal processing capabilities" patented technology

This invention provides a BTM enhanced antenna unit, including a first filtering circuit, a power supply and triggering circuit, a logic control unit, and a signal acquisition and decision circuit. The first filtering circuit is disposed between the power transmission loop of the antenna and the BTM, and is used to reduce harmonic radiation of the power transmission loop. One end of the power supply and triggering circuit is connected to the power receiving loop, and the other end is connected to the logic control unit, used to regulate the electrical signal on the BTM cable and output a trigger signal to the logic control unit. The signal acquisition and decision circuit is used to acquire the A4 interface signal, make a decision on the A4 interface signal, and output the decision result to the logic control unit. The logic control unit is used to control the acquisition and transmission of the A4 interface signal according to the trigger signal and the decision result. The BTM antenna unit of this invention has an energy judgment function, which improves the reliability of the BTM antenna, reduces the harmonic radiation of the BTM signal, and improves the compatibility between the antenna unit and the BTM.
