Modified Multiple Sub-blocking PTS Technique for Reduction in PAPR in OFDM System
Abstract: OFDM (Orthogonal frequency division multiplexing) is a multi-carrier modulation technique which provides better bandwidth efficiency at high data rate but the problem is it increases the PAPR. This increase in PAPR leads to loss of signal and in order rectify it cost of amplifiers has to be increased. Therefore, peak-to-average power reduction (PAPR) reduction is an important issue which is required to be solved. PAPR can be reduced by using …

PAPR Reduction in OFDM Using DCT Precoded SLM Technique
Abstract: Orthogonal frequency division multiplexing (OFDM) is a particular form of multi-carrier modulation. OFDM is a combination of modulation and multiplexing which is robust against the multipath effect, intersymbol interference and high spectral efficiency. However, peak-to-average power ratio (PAPR) is a major drawback in the system since this leads to the distortion problem in the linear devices such as the power amplifier (PA). Thus, the PAs require a back-off which is …
