To obtain good trade-offs between complexity and performance on peak-to-average power ratio reduction in orthogonal frequency division multiplexing using partial transmitting sequence schemes,a trellis structure based PTS factor search method is proposed.

为了得到部分传输序列降低OFDM信号峰均比方案中复杂度和性能之间的良好折衷，提出了一种基于格形结构的部分传输序列因子的搜索方法。

Results show that sulfides can be refined and disperse evenly after continuous multi-pass rolling, with the average width of sulfides being 4.91μm, the average length being 14.27μm, the average aspect ratio being 3.03, and the average area being 44.72μm2. The sulfides can refine the microstructure due to their pinning effect, and the reefing effect shows Zener relation.
