Résumé: The performances of multicarrier techniques in a spectrum coexistence context are commonly investigated using the power spectral density (PSD) of the coexisting systemsâ€™ signals. However due to many factors, the PSD approach does not lead to accurate results. Recently, a useful tool called â€œinstantaneous interference tablesâ€ has been proposed as an alternative to the PSD-based method leading to more accurate evaluation. This paper investigates the accuracy of the performance evaluation when the interference modeling is based on the PSD of the transmitted signals. With this aim in mind, two multicarrier schemes are examined: cyclic pre fix based orthogonal frequency division multiplexing (CP-OFDM) with a rectangular pulse shape and filter bank based multicarrier (FBMC) with PHYDYAS and IOTA waveforms.
