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 …
