The searching phase factors of partial transmit sequence (PTS) algorithm can be formulated as a combinatorial optimization problem with some variables and constrains, thus a modified discrete particle swarm optimization (DPSO) is applied to search the optimal combination of phase factors in this paper. The hamming distance is used to adjust the velocity of particle swarm, which makes the phase factors always move to the best phase factors, thus the orthogonal frequency division multiplexing (OFDM) signals with good peak-to-average power ratio (PAPR) performance can be achieved with low search complexity. To validate the analytical results, some simulations have been conducted, showing that the proposed schemes can achieve good PAPR performance with low computational complexity.

“…Numerous P APR reduction techniques have been proposed to solve this problem in recent years, such as clipping, coding and scrambling techniques [3]- [5]. As a scrambling technique, partial transmit sequence (PTS) [6]- [10] is known to achieve high PAPR reduction with a small amount of redundancy.…”

The iterative partial transmit sequences (IPTS) is an efficient algorithm to reduce the peak-to-average power ratio (P APR) in orthogonal frequency division multiplexing (OFDM), but its linear approach is easy to be trapped in a local optimum solution, thereby, an improved IPTS (I-IPTS) algorithm is proposed. In the proposed algorithm, it breaks out of the linear search, and set the phase factor achieved by the previous iteration as the initial phase factor of the current search, thus the search is more close to the optimal phase factor after repetition. Simulation results show that I-IPTS algorithm can achieve good PAPR performance with low computational complexity, thus has high feasibility.

“…To reduce the PAPR of OFDM signals, various techniques have been proposed in the literature [5], including clipping [6], coding technique [7], nonlinear companding transforms [8], selected mapping (SLM) [9], partial transmit sequence (PTS) [10,11], constellation modification [12] , and tone reservation [13]. Among these techniques [1], the PTS method is an attractive and important technique due to it has a good performance in terms of PAPR reduction.…”

Peak-to-Average Power Ratio (PAPR) reduction is an attractive research topic among the OFDM transmission research communities. Partial Transmit Sequence (PTS) has been a promising candidate out of the proposed PAPR reduction techniques without any distortion. In any PTS system, partitioning of the OFDM frame into disjoint sub-blocks is a crucial step. Adjacent partitioning (AP) is a rather simple partitioning scheme achieving attractive PAPR reduction performance. In this paper, we investigate effects of the length variability of disjoint sub-blocks on AP based PTS systems. In order to compare performance of variable length adjacent partitioning with the ordinary PTS scheme, we simulated other partitioning schemes, namely, interleaved, pseudorandom and fixed length adjacent partitioning for various types of modulation. Simulation results showed that the variable length adjacent partitioning is better than interleaved partitioning. However, it has worse PAPR reduction performance compared to the traditional adjacent and pseudorandom techniques. Keywords-adjacent partitioning PTS (AP-PTS); orthogonal frequency division multiplexing (OFDM); peak-to-average power ratio (PAPR); partial transmit sequences (PTS)I.
