Description: Reduction of peak-to-average power ratio (PAPR) in
orthogonal frequency-division multiplexing (OFDM) system using
the partial transmit sequence (PTS) approach. In PTS, the total
search for the number of subblocks and the rotation factors must
be accomplished. As the number of subblocks and rotation factors
increases, PAPR reduction improves. The number of calculation
increases as the number of subcarriers increases, such that
complexity increases exponentially and the process delay occur
simultaneously. In this paper, a modified PTS scheme combined
with interleaving technique for PAPR reduction has been
presented. The scheme is very effective and avoids the use of any
extra Inverse Fast Fourier Transformations (IFFTs) as was done
in PAPR reduction by ordinary PTS technique when dividing the
various subcarriers into different subblocks. The simulation
result shows that PAPR performance is improved in comparison
with the modified PTS and computational complexity is reduced

Description: PTS的基本思想是：将输入的OFDM符号X，分割成V个互不重叠的独立的子序列Xv，每个子块向量大小相等且子块中没有继承原符号相应位置的取值为0。经过N点快速傅里叶逆变换后获得时域信号xv，再与相位旋转因子系数bv相乘，最后将每个子块的结果求和。然后将使PAPR最小的旋转因子的最佳组合作为边带信息传送给接收机以恢复信号。
在PTS方法中，可以通过改变子序列的分割方式降低系统计算复杂度和改善系统性能。有三种常用的分割方法：相邻分割、伪随机分割和交织分割。(The basic idea of the partial transmission sequence method (PTS) is to split the input OFDM symbol X into V independent non-overlapping subsequences Xv, each of equal size and no inheritance of the corresponding position of the original symbol in the sub-block to take the value of 0. After N-point fast Fourier inversion to obtain the time domain signal xv, and then multiply with the phase rotation factor bv, and finally sum up the results of each sub-block . The best combination of rotation factors that minimizes the PAPR is then transmitted to the receiver as sideband information to recover the signal.
In the PTS method, the system computational complexity can be reduced and the system performance improved by changing the segmentation of the subsequence. There are three commonly used segmentation methods: adjacent segmentation, pseudo-random segmentation, and interleaved segmentation.)
