Third-generation (3G) wireless systems are being driven by the desire to support innovative broadband multimedia services. Multicarrier modulation code division multiple access (MCM-CDMA) or orthogonal frequency division multiplexing code division multiple access (OFDM-CDMA) schemes can meet such demand, so they are broadly considered as effective methods for future wireless multimedia communications. Since variant OFDM-CDMA schemes will coexist for a long time, reconfigurable multimode transceivers, which are compatible with diverse OFDM-CDMA schemes, are indispensable for base station and mobile station. In this paper by exploiting the concept of software-defined radio (SDR), an SDR-based baseband discrete model for variant OFDM-CDMA schemes is developed. Moreover the corresponding matrix representation is addressed
