Improved Clipping Technique for Reducing the Peak to Average Power Ratio in OFDM Systems

Peak to Average Power Ratio (PAPR) is one of the disadvantages of OFDM system, which had been studied in several papers and reduced in several techniques. Clipping and filtering are an effective technique for reducing the PAPR in OFDM systems. It requires an accurate filtering to reduce the resulting in-band and out-ofband noise. In this paper, an improved clipping technique is proposed. The te...

Peak to Average Power Ratio Reduction of Ofdm Signal by Combining Clipping with Walsh Hadamard Transform

Wireless communications have been developed widely and rapidly in the modern world especially during the last decade. Orthogonal Frequency Division Multiplexing (OFDM) has grown to a popular communication technique for high speed communication. Besides of the advantages, one of main disadvantage of OFDM is high peak to average power ratio (PAPR). In this paper, a PAPR reduction method is propos...

Tone Reservation for Peak-to-Average Power Ratio Reduction in OFDM under Different Optimization Constraints

The high peak-to-average power ratio (PAR) of the transmit signal is considered to be one major drawback of orthogonal frequency-division multiplexing (OFDM) systems. This paper analyzes the tone reservation (TR) technique for PAR reduction. It is shown that the good performance of TR is paid with an increase in average transmit power. Therefore, an extension of the TR scheme is considered, whi...

Peak to Average Power Ratio Reduction for Multi-band OFDM System using Tone Reservation

OFDM and its extension Multi-band OFDM (MB-OFDM) are considered as the modulation schemes for many future communications systems. But these schemes cause high PAPR which should be reduced before power amplification otherwise non-linearities can occur. In this paper Tone Reservation method is used for OFDM PAPR reduction where a corrective signal is added to the original signal to reduce its PAP...

Peak to Average Power Reduction Technique in OFDM System

In this paper, OFDM based on Software-Defined Radio (GNU Radio) to reducing the peak to average power ratio is developed and tested. Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, whether wireless or over copper wires, used in applications such as...
