چکیده
High peak to average power ration (PAPR) in orthogonal frequency division multiplexing (OFDM) is an important problem, which increase the cost and complexity of high amplifiers. One techniques used reduce PAPR OFDM system tone reservation method (TR). In our work we propose a modified decrease with low compared conventional TR by process amplitudes at same time. An image size 128×128 as source data that transmitted using system. The proposed 2dB keeping performance unchanged. tested several numbers subcarriers; found reduced number subcarriers decreased.

Selective Tone Reservation method for PAPR reduction in SFBC-OFDM systems
The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...
متن کاملSelective Tone Reservation Method for PAPR Reduction of Spatially Multiplexed OFDM Systems
Tone Reservation (TR) is one of the well-known methods for PAPR reduction of Orthogonal Frequency Division Multiplexing (OFDM) systems. In this method some sub-carriers are reserved for PAPR reduction and the symbols in these sub-carriers are selected such that the PAPR of the OFDM frame is minimized. In this paper, the iterative algorithm introduced earlier for TR method in single antenna OFDM...
متن کاملPAPR Reduction in OFDM system Using Tone Reservation Technique
57 Abstract— OFDM (Orthogonal Frequency Division Multiplexing) is spectrally efficient modulation technique used for higher data rate transmission. Basically OFDM system is very effective technique in its way ,but main disadvantage is Peak to Average Power Ratio. This Ratio Must be reduce to perfom efficient communication. Different technique can be used to reduce it. Here in this paper propo...
متن کاملPAPR Reduction of OFDM signals using Tone Reservation Technique
Orthogonal frequency division multiplexing (OFDM), has recently attracted considerable attention because of its features to combat delay spread or frequency selective fading of wireless or wireline channels. One of the major drawbacks of OFDM is the peak-to-average power ratio (PAPR) which leads to an inefficient use of high power amplifiers (HPA) in communications systems. This paper present t...
متن کاملPAPR reduction scheme with selective tone reservation for OFDM signals
In this paper, we propose a peak-to-average power ratio (PAPR) reduction scheme with selective tone reservation. In this scheme, the preset peak reduction tone (PRT) set would be divided into M PRT subsets that can generate M time-domain kernels. The differences of the slopes for the phase responses of the M timedomain kernels would be considered to design the M PRT subsets in reducing the PAPR...
