PAPR Reduction Techniques in OFDM System
Orthogonal Frequency Division Multiplexing (OFDM) is one of the techniques against the multipath fading channel for wireless communications. However, the high Peak-to-Average Power Ratio (PAPR) problem of OFDM is a major drawback of multicarrier transmission system which leads to power inefficiency in RF section of the transmitter. This paper presents different PAPR reduction techniques with an...
متن کاملPAPR Reduction Techniques in OFDM System
orthogonal frequency division multiplexing is a technique for transmitting large data over radio waves. The main drawback of OFDM is Peak to average power ratio(PAPR). This paper present all proposed techniques to reduce PAPR. These proposed techniques show better performance to reduce PAPR.
متن کامل“PAPR Reduction techniques in OFDM System”: Review
Abstact-Communication is one of the most important features of life.With its risingdemands,thegrowth in the field of communication is also increasing. Initially, the signal in the analogdomain were sent but now, signal in the digital domain are being send more. Single-carrier waves are being switched by multicarrier for improved transmission. Multicarrier system like CDMA and OFDM are currently...
متن کاملOFDM System PAPR Reduction Using Pulse Shaping
The peak to average power ratio of the time domain envelope is an important parameter at the physical layer of the communication system using OFDM signalling. The signals must maintain a specified average energy level in the channel to obtain the desired Bit-errorrate. The peak signal level relative to that average defines the maximum dynamic range that must be accommodated by the components in...
متن کاملAnalysis and Comparison of PAPR Reduction Techniques in OFDM Systems
The destructive impact of fading environments and also bandwidth limitations are two main challenges which communication is dealing with them. These challenges can affect on the growth of wireless communication and even cause reliable communications and high data rate to be prevented. Thus, OFDM (Orthogonal Frequency Division Multiplexing) modulation by using of fast calculation hardwares such ...
