dc.description.abstractThe Partial Transmit Sequence (PTS) method with low computation complexity, called decomposition PTS sub-blocking was proposed which employs the radix-2 inverse fast Fourier transform (IFFT) for the signals at the middle stages of an N-point radix-2 IFFT and decimation in frequency (DIF) domain. This method (DIF-IFFT) can reduce the computation complexity relatively with keeping the better PAPR performance similar to other PTS techniques with using the same weighting factor. To improve computation complexity for the PTS method, the Extended Split-Radix inverse fast Fourier transform (SRIFFT) which can reduces the number of computation complexity was proposed. However, the PAPR reduction performance is the same as that for the radix-2 method. In this paper, we propose a new weighting factor technique in conjunction with DIF-PTS sub-blocking based on Extended Split-Radix IFFT technique called Improve PTS (I-PTS) which can improve both the PAPR performance and computation complexity without any increasing of side information. This paper presents the various computer simulation results to verify the effectiveness of proposed method. © 2012 IEEE.
