Abstract
Channel adaptive waveforms (CAWs) as an extension of channel adaptive modulation (CAM) have been shown to be a promising design concept for wireless communication systems in heterogeneous environments. In contrast to prior works, this letter investigates the performance gains for CAW based on channel capacity for cell-specific and user-specific system configurations for FilterBank MultiCarrier (FBMC) with offset quadrature amplitude modulation subcarrier modulation systems in consideration of required inter-user guard bands. The results show that the cell- and user-specific CAWs provide a low-complexity system design, which is capable of fighting the interference problem for systems without a cyclic prefix, thereby improving the cell capacity in urban and hilly environments up to 90%.
