A comparative study of FBMC prototype filters in doubly dispersive channels

Due to its numerous advantages, orthogonal frequency division multiplexing (OFDM) has been the broadband wireless access technology of choice for many wireless standards over the last decade. Recently, filterbank multicarrier (FBMC) technique is emerging as one of the alternatives to OFDM for next generation broadband wireless access systems. While there are several studies on FBMC in the literature, its potential merits over OFDM and possible implementation challenges in practical environments require further investigations. Purpose of the present paper is to review and emphasize the key benefits of FBMC technology, and provide a comparative study of different FBMC prototype filter designs in the literature under practical channel environments.
