چکیده

High Peak-to-Average Power Ratio (PAPR) is the one of the major drawback of the Orthogonal Frequency Division Multiplexing (OFDM) transmitted signal. Thus, a high-dynamic range amplifier is needed, which increases the cost of the system. In this paper, a new PAPR reduction technique using new phase sequence based on some existing scheme is proposed to reduce the high Peak-to-Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) signals. We have compared the proposed technique with the new SLM, PTS, Iterative flipping and Original schemes. Although all the others existing techniques like Partial Transmit Sequences (PTS), new Selective Mapping (SLM) and Iterative flipping schemes can reduce the Peak-to-Average Power Ratio (PAPR), but the computer simulation results shows that the Proposed technique can offer better Peak-to-Average Power Ratio (PAPR) reduction than new SLM, PTS, Iterative flipping techniques. But the proposed scheme is more computationally complex than the existing techniques.

Increasing the Performance of OFDM Systems by PAPR Reduction in PTS Technique using Election Optimization Algorithm

Orthogonal Frequency Division Multiplexing (OFDM) is a useful technology in wireless communications that provides high-rate data transmission in multipath fading channels. The advantages of OFDM systems are the high spectral efficiency and strong resistance to frequency selective fading. In OFDM systems, a large number of sub-carriers are used to modulate the symbols causing the time-domain OFD...

On the Comparative Performance Analysis of PAPR Reduction Techniques in OFDM System

Selected Mapping (SLM) and Partial Transmit Sequence (PTS) are two very well-known Peak-to-average Power Ratio (PAPR) reduction techniques for Orthogonal Frequency Division Multiplexing (OFDM) systems. Both these schemes show good PAPR reduction capabilities. However, for any PAPR reduction technique, the nature of spectral occupancy and the associated computational complexity also need to be t...

Hybrid SLM-PTS for PAPR Reduction in MIMO-OFDM

Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is a promising candidate for 4G broadband wireless communications. However, MIMO-OFDM inherited the problem of high Peak-to-Average Power Ratio (PAPR) from OFDM. Many PAPR reduction techniques were developed in last two decades to reduce the PAPR of OFDM, among them Partial Transmit Sequence (PTS) and Selected...
