【 摘 要 】

The filter bank based multicarrier communication (FBMC) is a technology for multicarrier communications which has been recently considered by standard committees as a substitute for orthogonal frequency division multiplexing (OFDM). This paper investigates the performance of FBMC systems using different prototype filters viz root raised cosine (RRC), isotropic weighted Hermite and prototype filter based on Fourier invariant signal and their comparison based on bandwidth time-width (BT) product and interference plots. The prototype filter based on Fourier invariant signal is a new step towards prototype filter design. The study reveals that the prototype filter based on Fourier invariant signal has properties similar to that of isotropic weighted Hermite so that it can be applied in FBMC. Numerical results and simulations are provided to illustrate the time-frequency localization of both isotropic weighted Hermite and the filter obtained by Fourier invariant signal.
