Increasing 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 Performance of OFDM System Using Modified SLM Approach
In the era of modern wireless technology Multicarrier communication is one of the more suitable and reliable communication techniques. Orthogonal Frequency Division Multiplexing (OFDM) is used as modulation technique in multicarrier communication. OFDM has numerous advantages over single carrier communication but in spite of the advantages it suffers from one major drawback that is OFDM signal ...
متن کاملPerformance 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 کاملPerformance Improvement of Ofdm System Using Papr Reduction
Orthogonal frequency division multiplexing (OFDM) signals have a generic problem of high peak to average power ratio (PAPR) which is defined as the ratio of the peak power to the average power of the OFDM signal. The drawback of the high PAPR is that the dynamic range of the power amplifier and digital-to-analog converter during the transmission and reception of the signal is higher. As a resul...
متن کاملPartial Transmit Sequence based Localized Single Carrier FDMA for PAPR Reduction in LTE Systems
“In this paper, we introduce partial transmit sequence (PTS) based method to decrease the peak-to-average power ratio (PAPR) of the localized single-carrier frequency division multiple access (LFDMA) in the uplink systems. For a clip rate of 0.1% with user subcarriers of 64, system subcarriers of 256 with four different phase sequences; the gain of PAPR for the suggested PTS based LFDMA system ...
