PAR reduction of an OFDM signal using partial transmit sequences [PDF]

open access: yesIEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002
The peak-to-average power ratio (PAR) of an orthogonal frequency division multiplexing (OFDM) signal can be substantially larger than that of a single carrier system. Partial transmit sequence (PTS) combining can improve the PAR statistics of an OFDM signal. For PTS, the search complexity increases exponentially with the number of subblocks. We present

Analysis of Hybrid PAPR Reduction Methods of OFDM Signal for HPA Models in Wireless Communications

open access: yesIEEE Access, 2020
Orthogonal Frequency Division Multiplexing (OFDM) suffers from a high Peak-to-Average Power Ratio (PAPR). Designing a High Power Amplifier (HPA) with high PAPR is not a wise technique as it roots the amplifier to operate in a non-linear region which is ...
