A method for realizing predistortion compensation processing for 5G NR in-band modulated signals includes configuring the modulator to output a continuous wave signal, switch the output frequency interval of the signal to be consistent with the 5G NR subcarrier bandwidth, and record the power value P0 corresponding to the current frequency through the power meter. The power measurement difference between all points and P0 is calculated and performs normalization, and generates a compensated channel impulse response after shaping filtering; converts it into a power compensation factor in the time domain; performs inverse Fourier transform to generate I and Q baseband signals; generates compensated baseband data; the generated baseband data is filtered, and an analog zero intermediate frequency signal is generated, which is input to the broadband demodulator for frequency conversion modulation of the 5G NR broadband signal. The method operates without the need to modify the device circuit in the channel.

A method for transmitting contents and user's interactions among multiple devices is provided. The method includes determining a group of object devices including a portion of the plurality of object devices, transmitting the data to the object devices of the determined group, receiving confirmation information from the object device which completes receiving of the data, among the object devices of the determined group, determining a clone device based on the received confirmation information. The transmitted clone information is used to transmit the data from the determined clone device to at least one object device which is not included in the object devices of the determined group among the plurality of object devices.
