A low peak average ratio wireless optical transmission method based on dynamic scalar adjustment is disclosed in the present invention. Different scalar adjustment coefficients are selected according to the time domain peak value of each OFDM symbol, and the symbols with extra-high peak value are compressed at a certain extent, so as to reduce the PAPR of the signals of a whole frame and improve the transmission performance. The method is easy to be realized because that the receiving end only needs to estimate the scalar coefficient multiplied at the transmission end by measuring average power of the received symbols. The improvement of the PAPR reduces the system request for the amplification and the LED light linearity, reduces the non-linear distortion of the signals in electrical domain and optical domain, and improves the receiving performance of the system. The drop of the PAPR also reduces the direct current bias needed at the transmission end, and reduces the power wastage of the ...
