Abstract:
In this paper the parametric linear combination pulse (IPLCP) is proposed. The IPLCP is a new family of Nyquist-I pulses with two additional degrees of freedom to minimize the inter-carrier interference (ICI) power in orthogonal frequency-division multiplexing (OFDM) based systems due to frequency offset. Theoretical and numerical simulations are shown to verify that the performance of the IPLCP outperforms other existing pulses.
