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 کاملAnalysis and Comparison of PAPR Reduction Techniques in OFDM Systems
The destructive impact of fading environments and also bandwidth limitations are two main challenges which communication is dealing with them. These challenges can affect on the growth of wireless communication and even cause reliable communications and high data rate to be prevented. Thus, OFDM (Orthogonal Frequency Division Multiplexing) modulation by using of fast calculation hardwares such ...
متن کاملImplementation of Tone- Reservation Technique for PAPR Reduction in OFDM
One of the major drawbacks of OFDM is high Peak to-Average Power Ratio (PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplifier. Tone Reservation (TR) is a technique designed to combat this problem by reserving a number of carriers (tones) in the frequency domain to generate a cancellation signal in the time domain to remove high peaks. However TR can...
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...
