چکیده
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 proposed technique is Tone reservation.

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 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 کاملTone Reservation Based on Fourier Transformed Sequence for PAPR Reduction in OFDM Systems
This paper presents a new technique to reduce the peak-to-average power ratio (PAPR) in OFDM system by insertion of extra semi-dummy sequence in frequency domain. The extra sequence is generated via Fourier transform of a number of the data modulated symbols. The proposed technique provides instant frequency domain process for the PAPR problem solution. For the 16PSK-OFDM system using 512 subca...
