PAPR 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...
متن کاملPAPR 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 کاملReducing Intercarrier Interference in OFDM Systems by Partial Transmit Sequence and Selected Mapping
Orthogonal Frequency Division Multiplexing (OFDM) is sensitive to the carrier frequency offset (CFO). We introduce the Peak Interference-to-Carrier Ratio (PICR) to measure the resulting intercarrier interference (ICI). This paper shows that PICR can be reduced by Partial Transmit Sequence (PTS) and Selected Mapping (SLM) approaches. In PTS, each block of subcarriers is multiplied by a constant ...
متن کاملPAPR Reduction of OFDM Signals using Partial Transmit Sequence and Clipping Hybrid Scheme
The Orthogonal Frequency Division Multiplexing is one of the widely used modulation techniques in the broadband wireless technology. One of the main problems is the high peak-to-average power ratio of transmitted signal due to the superposition of many subcarriers. This paper presents a new hybrid peak-to-average power ratio reduction technique, which combines a partial transmit sequence method...
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...
