PAPR Reduction of OFDM Signals Using Selected Mapping Technique
According to the demand of advance communication field there should be high data rate in addition to both power efficiency and lower bit error rate. This demand of high data rate can be fulfilled by the single carrier modulation with compromising the trade off between the power efficiency and bit error rate. Again in the presence of frequency selective fading environment, it is very difficult t...
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 کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
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 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 ...
