PAPR Reduction in OFDM system Using Tone Reservation Technique
57 Abstract— OFDM (Orthogonal Frequency Division Multiplexing) is spectrally efficient modulation technique used for higher data rate transmission. Basically OFDM system is very effective technique in its way ,but main disadvantage is Peak to Average Power Ratio. This Ratio Must be reduce to perfom efficient communication. Different technique can be used to reduce it. Here in this paper propo...
متن کاملPAPR 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 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 کاملPAPR Reduction for OFDM System using Companding Technique
Communication is one of the important aspects of life to exchange their information and thoughts. With the advancement in age and user's growing demands, there has been rapid exponential growth in the field of communications. Signals, which were initially sent in the analog domain, are being sent more and more in the digital domain these days. For better transmission, even single – carrier wave...
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...
