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 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 کاملSignal Scrambling Techniques for PAPR Reduction in OFDM Systems
In recent years, the communication industry has started focusing on fourth generation (4G) mobile communication systems. It is expected that 4G will provide a comprehensive and secure IP solution where voice, data, and multimedia can be offered to users at “anytime, anywhere” with higher data rates than previous generations. To improve spectrum efficiency and achieve as high as 100Mbps wireless...
متن کاملPAPR Reduction of OFDM signals using Selective Mapping and Partial Transmit Sequence
Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for broadband wireless transmission due to its robustness against multi-path fading. In multicarrier modulation, the most commonly used technique is OFDM, it has recently become very popular in wireless communication. The main drawback of OFDM is Peak to average power ratio (PAPR). This paper present sel...
