Abstract :
Combining multicarrier (OFDM) and CDMA technologies is attractive for future wireless broadband communications and software radio realization. Based on the unified framework known as OFCDMA, we develop a programmable structure for OFDM-CDMA transceivers in spite of three different scenarios to combine OFDM and CDMA. By adjusting system parameters without changing the fundamental hardware and software architecture, various system scenarios can be implemented, which might serve as the foundation to design software radio
