PAPR Reduction in OFDM Using Partial Transmit Sequence (PTS)
Absract -In recent years, OFDM has gained a lot of interest in diverse-digital communication applications. This has been due to its favorable properties like high spectral efficiency and robustness to channel fading. Some of the major drawbacks in OFDM are its high peak-to-average-power ratio(PAPR) of the transmitted signals and the synchronization of signals. OFDM consist of large number of in...
متن کاملPartial Transmit Sequence (PTS)-PAPR Reduction Technique in OFDM Systems with Reduced Complexity
OFDM systems have the inherent problem of a high peak to average power ratio (PAPR). OFDM Suffers as the no of Subcarriers operating in the large dynamic range operates in the non-linear region of amplifier due to OFDM suffer the PAPR problem Application of high power amplifiers results in increased component cost. In general, there has been a trade-off between PAPR reduction and computational ...
متن کاملThe Reduction of PAPR using CPM Mappers and Partial Transmit Sequence (PTS) Scheme in OFDM Systems
High peak-to-average power ratio of the transmit signal is a major drawback of multicarrier transmission such as OFDM. This paper describes Orthogonal Frequency Division Multiplexing (OFDM) system with Continuous Phase Modulation (CPM) mappers is considered. Such a system is known to provide superior bit error rate performance by virtue of the memory introduced by the CPM mapper compared to OFD...
متن کاملHybrid SLM-PTS for PAPR Reduction in MIMO-OFDM
Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is a promising candidate for 4G broadband wireless communications. However, MIMO-OFDM inherited the problem of high Peak-to-Average Power Ratio (PAPR) from OFDM. Many PAPR reduction techniques were developed in last two decades to reduce the PAPR of OFDM, among them Partial Transmit Sequence (PTS) and Selected...
متن کاملM-2m Mapping Scheme for Papr Reduction in Slm and Pts Based Ofdm Systems without Si
As discussed in chapter 3, selected mapping (SLM) and partial transmit sequence (PTS) are the two most popular distortion-less PAPR reduction techniques but both of them require the transmission of SI, with each OFDM symbol to recover the original OFDM signal. The transmission of SI not only reduces the effective data rate, but also degrades the error performance of the OFDM system, in case of ...
