| 摘要 |
<p>Disclosed is an orthogonal frequency division multiplexing (OFDM) modulation method, including: acquiring data to be encoded; performing phase-differential encoding on the data to be encoded; and performing inverse fast Fourier transform (IFFT) on the data to be encoded after phase-differential encoding to obtain a time domain signal of the OFDM. Also disclosed at the same time is an OFDM modulation device. The solution of the present invention can reduce calculations when performing OFDM modulation on the data, significantly reducing the peak average power ratio (PAPR) of OFDM modulation.</p> |
