    With the opening up of the white spaces, efficient use of the fragmented spectrum, particularly TV white space, has become an extremely important research focus. Apart from efficient spectrum usage, special care needs to be taken to maintain low out-of-band radiation to avoid harmful interference to the incumbent services, like TV signals and wireless microphones. For that purpose, a flexible digital radio with multicarrier modulation scheme is the only solution. In this paper we show the performance of two innovative multicarrier systems, Filter Bank Multi Carrier (FBMC) and Generalized Frequency Division Multiplexing (GFDM). A simple interference cancellation technique called serial intercarrier interference cancellation scheme have been used to improve the performance of the GFDM system. Channel equalization techniques have been implemented for FBMC.
