Performance Analysis of OFDM System Using PAPR Reduction Techniques
Orthogonal Frequency division Multiplexing (OFDM) is an efficient method of data transmission for high speed communication systems. However, the main drawback of OFDM system is the high Peak to Average Power Ratio (PAPR) of the transmitted signals. OFDM consist of large number of independent subcarriers, as a result of which the amplitude of such a signal can have high peak values. Coding, phas...
متن کاملA Novel Low Computational Complexity Multiple Signal Representation Technique for PAPR Reduction in OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) while being an efficient scheme for high data rate wireless communications has drawbacks such as higher Peak-to-Average Power Ratio (PAPR). To reduce PAPR, use of multiple signal representation technique such as Partial Transmit Sequence (PTS) is one of the favored techniques. However, the use of conventional PTS technique need excessive number ...
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 ...
متن کاملPAPR reduction of Coded OFDM signal using Selective Mapping Technique
Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation (MCM) technique which seems to be an attractive candidate for fourth generation (4G) wireless communication systems. Peak-to-average Power ratio(PAPR) problem is the major drawback of multicarrier transmission system which leads to power inefficiency.There are various techniques which can be used to reduce PAPR.In th...
