Prior technology: '' Wireless communication is a method that uses radio waves to transmit signals from the transmitting end to the receiving end. 'Because radio waves have the advantages of fast transmission speed and wide transmission range, the application of wireless communication has become increasingly popular, and related development has become faster. Its main basic structure includes a transmitter located at the transmitting end and a receiver located at the receiving end; the transmitting end uses the transmitter to encode, modulate and amplify the signal, and transmits the signal to the receiver through radio waves, and then The receiver decodes, demodulates and amplifies the signal, and finally the signal is restored and output by the receiving end.

(power amplifier, referred to as PA), which is related to phase lock Ring 13 gives 595133 to send it to a distance. The receiving and transmitting funnel 10 includes a selective receiving antenna, a low noise amplifier 18 (low noise amp 1 ifier, LNA for short), a mixer 19, a / boge 20 and a demodulator 21 ( demodulati〇n). After receiving the signal sent by the transmitter (or transceiver) of the receiver, the receiving antenna 17 must first pass through the low-noise amplifier 18, the mixer 19, and the filter 20, and then demodulate it. The converter 21 demodulates the signal, converts it into the original signal and outputs it. Generally speaking, in order to improve the distance and efficiency of signal transmission, the transceiver usually does not directly transmit the original signal, but converts the original signal to another waveform suitable for the transmission medium before transmitting. Such waveform conversion is called It is "modulation"; similarly, the transceiver must convert the modulated signal into the original signal after demodulating the received signal. At present, the commonly used signal modulation techniques mainly include binary modulation (on-off keying (referred to as 00K)), amplitude shift keying (referred to as ASK), frequency shift keying (referred to as FSK), phase shifting Phase shift keying (PSK), etc. The modulation and demodulation of the signal must be relative, that is, if the signal is modulated by a certain technology during the transmission process, it must also be the same when demodulated. Technology can restore the signal.

'It will not be possible to demodulate the signals transmitted by the conventional technology and transceiver' because the signals transmitted by the transmitter of the conventional technology are modulated by the frequency shift key (fs κ) . This will cause great confusion for users or transceiver manufacturers. For example, many car anti-theft devices (or iron roll doors) are still designed to set functions by wireless signal transmission. The anti-theft device is equipped with a wireless signal receiver (or transceiver), and a wireless signal transceiver is provided on the vehicle owner's body. Since most of the receivers (or transceivers) of the anti-theft device are still used for signal demodulation, The modulation in the form of carry (00K) is mainly used, so that the transceiver on the vehicle owner must also be modulated with the technology of binary modulation (00K). However, at present, the frequency shift key (FSK) technology is used to modulate and demodulate signals. There has been a trend to gradually replace the binary form of modulation technology (00K). Therefore, the current receiver (transceiver) inside the car alarm has The signal may be demodulated by frequency shift key (FSK), or it may be demodulated by binary modulation technology (00K), and the transceiver on the vehicle owner can communicate with the receiver inside the car alarm ( Transceiver) distribution valley must also be designed for specifications with FSK and 00K signal modulation functions, which will cause considerable confusion for manufacturers and users.
