A Modified PTS Method Using m Sequences for PAPR Reduction
For the disadvantage of degrade PAPR property of the existing methods using m sequences in traditional way, which is too simple in the aspects of the conversion from m sequences to rotation factors, an improved algorithm of PTS is proposed. This method can obtained the matrix, depending on the rotation factors including four phases (l,-lj,-j) by using m sequences, to reserch, so the scope of choice is expanded, and the PAPR of OFDM system is greater reducted. The results of the simulation show that compared to the methods using m sequences in traditional way , the modified method basically doesn t increase the complexity of the system, while PAPR has been in a situation of better control.
