Abstract

Several techniques have been proposed to address the problem of high sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM) systems. Frequency offsets results in intercarrier interference (ICI) which eventually degrades the performance of the overall system. The most common approach being used to suppress the effects of ICI power in OFDM systems is a pulse-shaping technique. Two novel families of Nyquist-I pulses are proposed to minimize the ICI power and increase signal-to-interference ratio (SIR) power in OFDM-based systems. The proposed pulses are characterized by novel design parameters which provide extra degrees of freedom for a certain value of roll-off factor, α. The proposed pulses are examined with respect to ICI power and SIR in OFDM system. We evaluate and compare the performance of the proposed pulses with other recommended pulses for OFDM systems. Simulation results show that the proposed pulses performed better than other existing pulses in terms of ICI power and SIR for OFDM systems.
