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 کاملAn Efficient PAPR Reduction Method for LTE OFDM Systems
This paper reviews orthogonal frequency division multiple (OFDM) which has been adopted as a standard for various high data rate wireless communication systems. However, implementation of the OFDM system entails several difficulties. One of the major drawbacks is the high peak-to-average power ratio (PAPR) which cause large number of sub-carriers, that make restrictions for practical applicatio...
متن کاملClipping Based PAPR Reduction Method for LTE OFDMA Systems
Long term evolution (LTE) is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. LTE has adopted orthogonal frequency division multiplexing (OFDM) for the downlink transmission. OFDM meets the LTE requirement for spectrum flexibility and enables cost-efficient solutions for very wide carriers with high peak...
متن کاملBER and PAPR Reduction Method for Nonlinearly Amplified OFDM Signals
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), ...
