- Abstract:
- 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 by varying LC consecutive factors.The trellis search can be viewed as a general PTS factor search model.If LC=V-1, it is a full search, and if LC=1, it is an iterative search.Using different constraint lengths, trellis factor search PTS exhibits different PAPR reduction performances.A larger LC results in a better performance and LC=V-1 results in the optimum.However, a larger LC requires more computation.This helps to choose a good trade-off between complexity and performance.
