PAPR Reduction in OFDM System Using PTS+DCT+SLM Technique

Sweety Narula, Ritesh Beohar

In communication system the operation of the transmitter power is limited to some range and if the input signal with an amplitude more than the transmitter power amplifier linear range results in signal distortion. Since now the demand for multimedia data services has grown up rapidly one of the most promising method is considered as the OFDM (Orthogonal frequency division multiplexing).Since the subcarriers, high data rate, ubiquitous coverage with high mobility and many such features not only enhances the usability of the system but has given a major disadvantage too. Peak-to-average-power ratio (PAPR) has highly affected the OFDM system. The high the PAPR in the signal it will occasionally drive high power amplifiers (HPAs) to operate in the nonlinear region of their characteristic curve. Here the nonlinearity can cause loss of orthogonality amongst the carrier causing inter carrier interference (ICI) in signal. In-band and Out-band radiations are also outcomes of the PAPR. In this paper we will implement techniques to low the PAPR.
