OFDM (Orthogonal Frequency Division Multiplexing) signal peak-to-average power ratio inhibition method based on distributed implementation

The invention discloses an OFDM (Orthogonal Frequency Division Multiplexing) signal peak-to-average power ratio inhibition method based on distributed implementation, mainly solving the problem of high complexity when the current inhibition OFDM system inhibits a peak-to-average power ratio. The method comprises the following steps: setting an OFDM system peak-to-average power ratio threshold, an idle subcarrier power amplitude limiting threshold and an OFDM symbol pilot subcarrier power constraint which meet requirements of an occasion of the system, and then combining with original OFDM frequency domain symbols and relevant initial variables to establish a non-convex optimization model; then, carrying out relaxation conversion on the model and solving to obtain an expected OFDM frequency domain symbol; and at last, enabling the expected OFDM frequency domain symbol to send out via an antenna after successively undergoing IFFT, parallel-serial conversion, cyclic prefix addition, D/A conversion and radio-freq
