基于格形因子搜索的部分传输序列方法OA
Partial transmitting sequence method based on trellis factor search
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.这种格形搜索有一个可变的约束长度LC,1≤LC≤V-1,V为部分传输序列子块的数目.该方法通过搜寻格形结构中可能的路径来决定部分传输序列的因子,而这些路径通过改变LC个相邻因子的值得到.格形搜索可看作一个统一的传输序列因子搜索模型,当LC=V-1,为全局搜索;当LC=1,为单步迭代搜索.采用不同的约束长度,格形搜索在抑制…查看全部>>
To obtain good trade-offs between complexity and performance on peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) using partial transmitting sequence (PTS) schemes,a trellis structure based PTS factor search method is proposed.The trellis search is with a variant constraint length LC,1≤LC≤V-1,where V is the number of PTS subblocks.The method is to decide a PTS factor by searching all the possible paths obtained…查看全部>>
