A NEW DISCRETE HARTLEY TRANSFORM PRECODING BASED INTERLEAVED-OFDMA UPLINK SYSTEM WITH REDUCED PAPR FOR 4G CELLULAR NETWORKS [PDF]

Journal of Engineering Science and Technology, 2011
High peak-to-average power ratio (PAPR) reduction is one of the major challenges in orthogonal frequency division multiple access (OFDMA) systems since last decades. High PAPR increases the complexity of analogue-to-digital (A/D) and digital-to-analogue (

A novel generalized oppositional biogeography-based optimization algorithm: application to peak to average power ratio reduction in OFDM systems

Open Mathematics, 2016
A major drawback of orthogonal frequency division multiplexing (OFDM) signals is the high value of peak to average power ratio (PAPR). Partial transmit sequences (PTS) is a popular PAPR reduction method with good PAPR reduction performance, but its ...

Peak to Average Power Ratio Reduction of OFDM Signals Using Clipping and Iterative Processing Methods

Al-Khawarizmi Engineering Journal, 2008
One of the serious problems in any wireless communication system using multi carrier modulation technique like Orthogonal Frequency Division Multiplexing (OFDM) is its Peak to Average Power Ratio (PAPR).It limits the transmission power due to the ...

A peak-to-average power ratio reduction algorithm for OTFS systems in satellite-to-ground scenarios

Dianxin kexue
Orthogonal time frequency space (OTFS) modulation is shown to enable reliable communication in high-Doppler environments, making it suitable for high-mobility scenarios such as satellite communication. However, its high peak-to-average power ratio (PAPR)
