Peak-to-average power ratio (PAPR) plays an important role in the design of wireless communication systems because a high PAPR decreases the efficiency of the power amplifier. A new family of Nyquist pulses was derived by applying a linear combination between two Nyquist pulses. The proposed Nyquist pulses are utilized for pulse shaping to reduce PAPR. The investigated pulses are characterized by a new design parameter (p
), giving an additional degree of freedom to minimize PAPR for a given roll-off factor α
. While keeping the same bandwidth, the frequency responses of the proposed filters are unique with different values of the parameter p
. Simulations showed that the optimum proposed pulse shaping filters provide better performance in PAPR reduction compared to those of the RC filter and other existing filters evaluated in various systems.
