Abstract

In this work, the performance of the sub-optimum improved parametric linear combination pulse (IPLCP) in orthogonal frequency division multiplexing (OFDM) based systems is evaluated. An OFDM-based system, in the presence of carrier phase noise and carrier frequency offset, is evaluated in terms of BER. The IPLCP is characterized by having three additional design parameters, adding extra degrees of freedom to reduce the BER in OFDM-based systems. Two of the constants were fixed, whereas the other one was optimized via numerical simulations for BER reduction. The sub-optimum IPLCP outperforms the other evaluated pulses in terms of BER.
