چکیده
Orthogonal Frequency Division Multiplexing (OFDM) is one of the Strong candidate for Transmission of high data rate due to Multicarrier Modulation. One of the challenging Issue of OFDM is its high Peak to Average Power Ratio (PAPR or PAR). This Paper discusses different PAPR Reduction techniques in OFDM. The Classical Clipping, Selective Mapping, Tone reservation and Partial Transmit sequence Technique is used in this paper. Through the Analysis, it is shown that Clipping on 4-PAM is better than QPSK and 4-QAM with 64 subcarriers and Classical clipping is better than other techniques using QPSK modulation with 64 subcarriers.

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...

Multicarrier modulations have become broadened and Orthogonal Frequency Division Multiplexing (OFDM) has been widely implemented in high speed digital modulations. OFDM is a multicarrier transmission technique which divides the available spectrum into many carriers, each one being modulated by a low rate data stream. One major disadvantages of OFDM is that the time domain OFDM signal which is a...

متن کاملAn 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...
