Paper Abstract

The raised cosine is a bandwidth efficient pulse shaping waveform with relatively high peak to average power ratio (PAPR) for smaller excess bandwidths. Reducing the PAPR while maintaining the shaped waveform integrity and bandwidth efficiency increases the transmission rate by utilizing the spectrum more effectively. In this paper, we modify the raised cosine by reducing the adjacent symbol contribution to the PAPR with small increase in the Error Vector Magnitude (EVM) and the required bandwidth over the raised cosine waveform. The attained PAPR reduction is on the order of 1.5 dB for the smaller excess bandwidth.
