Patent ID: 7660360

Claim:
A method for reducing peak-to-average power ratio (PAPR) of a coded orthogonal frequency-division multiplexing (OFDM) system comprising: modulating label-inserted, coded bits into symbols; applying an inverse discrete fourier transform (IDFT) on said symbols to produce OFDM signals having different PAPRs due to insertion of sequences of label bits into a stream of information bits, wherein each OFDM signal corresponds to a different sequence of label bits; selecting a threshold PAPR by considering the average number (u) of said sequences and corresponding OFDM signals evaluated for PAPR measurements before finding an OFDM signal with a PAPR that is less than said threshold PAPR; and transmitting one of the OFDM signals to a receiver if a PAPR of said one of the OFDM signals is less than the threshold PAPR.
