Abstract: A signal processing method is applied to an RFID electronic tag, and includes: coding a digital baseband signal to obtain a coded signal; performing phase-shift keying modulation on the coded signal to obtain a first modulated signal; performing OFDM modulation on the first modulated signal to obtain a second modulated signal; and sending the second modulated signal to an RFID reader, by means of which the OFDM demodulation, phase-shift keying demodulation, and decoding are performed sequentially on the second modulated signal. According to the signal processing method and device, and the RFID system of one or more embodiments of present disclosure, the RFID system can be caused to effectively utilize bandwidth, thereby achieving high-speed transmission of signals and significantly reducing a bit error ratio of signal transmission.

Abstract: The present disclosure discloses a storage method, a data processing method, a device and an apparatus based on a non-volatile memory, the method comprising: acquiring a weight value that needs to be stored in the non-volatile memory; determining a conductivity value corresponding to the weight value according to a first conversion method if the non-volatile memory is a high-resistance storage device; determining a conductivity value corresponding to the weight value according to a second conversion method which is different from the first conversion method if the non-volatile memory is a low-resistance memory device; and setting the non-volatile memory according to the conductivity value to store the weight value. The non-volatile memory and the data processing method, the device, and the apparatus provided by the present disclosure solve the problem of insufficient accuracy in weight values in existing non-volatile memories, realizing the technical effect of improving storage accuracy and data processing accuracy.
