Method and device for processing orthogonal frequency division multiplexing signals

Abstract

The embodiment of the invention provides a method and a device for processing orthogonal frequency division multiplexing signals. The method comprises the following steps: selecting a part of subcarriers from subcarriers of an orthogonal frequency division multiplexing (OFDM) signal as reserved subcarriers; and reducing the peak to average power ratio (PAPR) and integral sidelobe level (ISL) of the OFDM signal by setting the power of the first time domain sequence corresponding to the OFDM signal and the power of each modulation symbol of the reserved subcarrier. According to the embodiment of the invention, the problem that the PAPR and ISL of the OFDM signal need to be reduced when the OFDM signal is used as the communication and inductance integrated waveform in the related technology can be solved, and the effect of improving the sensing capability of the communication and inductance integrated system is achieved.
