چکیده

This paper presents a new technique to improve the performance of OFDM systems with nonlinear amplifiers. This method aims to achieve good balances between PAPR and BER at low computer cost. A performance and complexity comparison with known techniques for BER reduction is presented. The results show that the proposed method has lower computational complexity (about 33% fewer multiplications), similar BER performance and better PAPR performance than the other techniques here evaluated. Keywords— OFDM, PAPR, BER Reduction, PTS, nonlinear amplifiers.

An Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information

Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...

Analysis 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 ...

Selective 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...

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...

PAPR Reduction in OFDM System Based on MODIFIED COMPANDING Technique

In the below paper we have proposed a novel companding transform using the concept of median as in statistics and based on A-law companding which reduces the Peak-to-Average Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) signals. This companding transform is unlike the traditional μ-law companding which is solely based on only expanding the small signals thus increasing the a...
