Enhanced Partial Transmit Sequence (PTS) approach utilizing M-sequence to reduce Peak-to-Average Power Ratio (PAPR) in OFDM transmissions
Detailed Documentation
The paper presents a modified Partial Transmit Sequence (PTS) technique for OFDM systems that employs M-sequences to effectively reduce Peak-to-Average Power Ratio (PAPR). This implementation typically involves partitioning OFDM subcarriers into disjoint blocks, applying phase rotation factors generated through M-sequence algorithms, and selecting the optimal combination that minimizes peak power. Key computational steps include generating M-sequence based weighting vectors, calculating multiple candidate signals through inverse fast Fourier transform (IFFT), and implementing peak power comparison algorithms to identify the transmission signal with minimized PAPR characteristics.
