PAPR Reduction in MIMO-OFDM System using Clipping Technique
Orthogonal Frequency-Division Multiplexing (OFDM) is a multicarrier transmission scheme. It has various advantages like easy and efficient in dealing with multi-path, robust against narrow-band interference, supports various modulation schemes and perfect for Multiple Input Multiple Output (MIMO) technique. OFDM is combined with MIMO, called MIMO-OFDM. This improves the bandwidth efficiency of ...
متن کاملA New Peak Clipping Algorithm for PAPR Reduction in OFDM
The peak-to-average-power ratio (PAPR) is one of the major problems of Orthogonal Frequency Division Multiplexing (OFDM) systems. Various PAPR reduction techniques have been given in the past. Among these techniques, the clipping technique has been widely adopted as a practical scheme because of its low computational complexity and simplicity in implementation, while the pre-coding technique is...
متن کاملIncreasing the Performance of OFDM Systems by PAPR Reduction in PTS Technique using Election Optimization Algorithm
Orthogonal Frequency Division Multiplexing (OFDM) is a useful technology in wireless communications that provides high-rate data transmission in multipath fading channels. The advantages of OFDM systems are the high spectral efficiency and strong resistance to frequency selective fading. In OFDM systems, a large number of sub-carriers are used to modulate the symbols causing the time-domain OFD...
متن کاملClipping Technique for BER and PAPR Reduction in OFDM System
Peak to Average Power Ratio (PAPR) is one of most detrimental aspects in any wireless communication system using multicarrier modulation technique like OFDM, which cause power degradation and spectral spreading. Due to the simplest way for PAPR reduction, clipping technique has been proposed and seems to be promising for use in commercial system. In this paper, we mainly focus on Amplitude clip...
