Power loading for FBMC systems: An analysis with mercury-filling approach

This paper tackles the problem of efficient power loading in Filter-Bank based Multicarrier (FBMC) systems, being more and more often treated as the potential successor of the Orthogonal Frequency Division Multiplexing (OFDM) scheme. In particular the potential of application of the mercury-waterfilling principle for power allocation among data symbols in these systems has been analyzed. The efficiency of the proposed link adaptation scheme has been verified in the specified WiMAX-PUSC scenario, in which dedicated pilot pattern, adapted to the FBMC features, was used.
