Enhanced Sub-Block Partitioning and Effective Post-Processing for the PTS Algorithm
Main Article Content
Abstract
The transmitted OFDM is a multicarrier modulation technique for efficient and reliable data communication. This technique forces a major problem during the signal transmission process, which is a high peak-to-average power ratio (PAPR), leading to significant performance degradation when employing a nonlinear power amplifier. The traditional Partial Transmit Sequence (PTS) scheme is a popular PAPR reduction technique. The PTS technique involves three approaches for sub-block partitioning to mitigate PAPR: adjacent (AD), interleaved (IL), and pseudorandom (PR) partitioning. This paper presents a hybrid reduction technique that combines IL partitioning with the AD scheme, enhancing the PTS sub-block partitioning approach. The proposed technique is further improved by hybridizing it with two other simpler methods, such as Mu-Law companding or post-processing phase clipping, to enhance the reduction capability. Simulation outcomes demonstrate that this approach achieves a more substantial PAPR reduction, even surpassing the performance of PR partitioning, which is commonly considered the most efficient PAPR reduction technique.
