In the PTS, as sub-blocks increase, the performance of reducing peak-to-average power ratio (PAPR) is getting better, but complexity grow exponentially. The first method is to reduce the complexity of PTS by iteration, and uses the information obtained from last time to get better performance, so it can use less sub-blocks to get the same performance as PTS .The second method is to reduce much complexity by modified tree structure than RC-PTS. The last is to reduce complexity of tree structure by Fano algorithm, and changes the parallel form of tree structure into series form. In this method, we also add the threshold to let complexity lower. Hou-shou Chen 陳後守 2016 學位論文 ; thesis 63 zh-TW |
