Crest Factor Reduction in MC-CDMA Employing Carrier Interferometry Codes

open access: yesEURASIP Journal on Wireless Communications and Networking, 2004
This paper addresses signal compactness issues in MC-CDMA employing carrier interferometry codes using the measure of crest factor (CF). Carrier interferometry codes, applied to -carrier MC-CDMA systems, enable users to simultaneously share the system ...

Interference-Aware PAPR Reduction Scheme to Increase the Energy Efficiency of Large-Scale MIMO-OFDM Systems

open access: yesEnergies, 2017
Large-scale (LS) multi-user (MU) multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) is considered to be a desirable signal transmission scheme because it can significantly improve the energy efficiency (EE) and spectral

Peak to Average Power Ratio Reduction Techniques

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2021
Multiple-input to multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) are the utmost widely used wireless communication system because of its large benefits and advantageous. Though MIMO OFDM systems have high advantages there is a major drawback that makes the system noisy and the inefficient use of bandwidth.

Peak-to-Average Power Ratio of Good Codes for Gaussian Channel

open access: yesIEEE Transactions on Information Theory, 2014
Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength. In this paper it is shown that codes achieving this tradeoff must necessarily have peak-to-average power ratio (PAPR ...

PEAK-TO-AVERAGE POWER RATIO REDUCTION OF OFDM SIGANLS

open access: yesInternational Journal of Research in Engineering and Technology, 2012
Orthogonal frequency division multiplexing (OFDM) is a form of multicarrier modulation technique with high spectral efficiency and immunity to interference. Despite of many advantages the main disadvantage of OFDM is that the time domain of OFDM signal which is a sum of subcarrier sinusoids leads to high Peak-to-Average power ratio (PAPR).

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

open access: yesAl-Khawarizmi Engineering Journal, 2019
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 ...
