A novel family of Nyquist-I pulses called iPOWER is proposed with a new design parameter that provides an extra degree of freedom for a certain roll-off factor. The proposed pulse is examined and compared with other existing pulses in terms of out-of-band (OOB) power, intercarrier interference (ICI) power, signal-to-interference ratio (SIR) power, and bit-error-rate (BER) in orthogonal frequency division multiplexing (OFDM) systems. The BER was analyzed in the presence of carrier frequency offset (CFO), which introduces ICI in OFDM-based systems. Eye diagram tool is also used to visually analyze the performance of the proposed pulse. Simulation results show that the iPOWER pulse performs better in terms of OOB power, ICI power, SIR power, and improving BER in comparison to other existing pulses in OFDM-based systems.
