Paper Abstract

The raised cosine waveform is a common efficient waveform to control the bandwidth reduction of a communications signal at the cost of controlled Inter Symbol Interference (ISI) with relatively large Peak to Average Power Ratio (PAPR). Reducing the PAPR has been addressed extensively in the literature using methods such as the clipping and coding the data among others. In this paper, we reduce the PAPR by windowing the raised cosine waveform to minimize contributions to PAPR with minimal spectral growth. We simulate the modified raised cosine to determine the reduction in PAPR for various Quadrature Amplitude Modulation (QAM) orders and excess bandwidths.
