Abstract
A method for avoiding transmission of side information by a Partial Transmit Sequence, comprising the following steps: Step 1: determining an indication sequence of a data sub-carrier and a pilot sub-carrier; Step 2: grouping the frequency domain data blocks including data and pilots to reduce the peak-to-average power ratio (PAPR) of the OFDM signal by phase rotation according to the PTS method. Step 3: processing the pilot of the received signal through channel estimation based on fast Fourier transform interpolation to obtain a frequency domain channel response, and extracting a phase rotation sequence. Step 4: equalizing the received data through the obtained frequency domain channel response. Step 5: performing inverse rotation of phase on the equalized data through the phase rotation information extracted in Step 3 to obtain transmitted data symbols.
