--------------------------------------------------------------------ABSTRACT-------------------------------------------------------------------------Multi-carrier modulation is an attractive technique for fourth generation wireless communication. Orthogonal Frequency Division Multiplexing (OFDM) is multi-carrier transmission scheme. Its high Peak to Average Power Ratio (PAPR) of the transmitted...
متن کاملAn Improved SLM Technique For PAPR Reduction In OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) is widely used as a standard modulation for various high data rate wireless communication systems. It is worked by converting high data rate streams into a number of parallel low data rate streams. OFDM has many advantages over single carrier modulation systems. Some of these advantages are robustness to frequency fading channels, high transmiss...
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...
متن کاملPerformance Analysis of Pulse Shaping Technique for OFDM PAPR Reduction
Orthogonal Frequency Division Multiplexing (OFDM) is an attractive modulation and multiple access techniques for channels with a nonflat frequency response, as it saves the need for complex equalizers. It can offer high quality performance in terms of bandwidth efficiency, robustness against multipath fading and cost-effective implementation. However, its main disadvantage is the high peak-to-a...
متن کاملImplementation of Tone- Reservation Technique for PAPR Reduction in OFDM
One of the major drawbacks of OFDM is high Peak to-Average Power Ratio (PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplifier. Tone Reservation (TR) is a technique designed to combat this problem by reserving a number of carriers (tones) in the frequency domain to generate a cancellation signal in the time domain to remove high peaks. However TR can...
