Filterbank Multicarrier and Multicarrier CDMA for Cognitive Radio Systems [PDF]
2007 2nd International Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2007 Recent works in cognitive radio (CR) have suggested multicarrier communication based on orthogonal frequency-division multiplexing (OFDM) for CR networks. In this paper, we propose two alternative multicarrier techniques. The first one, filterbank-based OFDM-OQAM (OFDM-offset quadrature amplitude modulation), allows to maximize the secondary users ...

Multi-code Multicarrier CDMA: Performance Analysis
Journal of Communications Software and Systems, 2004 A new multi-code multicarrier code division multiple access (MC-MC-CDMA) system is proposed and analyzed in afrequency selective fading channel. By allowing each user to transmit an M-ary code sequence, the proposed MC-MC-CDMA system can support various data rates as required by next generation standards without increasing the interference which is ...

Multicarrier CDMA Overlay for Ultra-Wideband Communications [PDF]
IEEE Transactions on Communications, 2004 In this letter, the performance of multicarrier code-division multiple-access (CDMA) systems is studied in the presence of narrowband interference for future ultra-wideband (UWB) communications. A Nakagami fading channel is assumed, and notch filters along with diversity techniques are used in the multicarrier CDMA receiver.
