OFDM, SC-FDMA AND MC-CDMA educational wireless transceivers using Matlab and the TMS320C6713 DSK

In this paper we describe the design and implementation of real-time wireless transceivers for advanced multicarrier modulation schemes, namely OFDM, SC-FDMA and MC-CDMA. The baseband system level design is done using Matlab/Simulink and the implementation is done using the TMS320C6713 DSK from Texas Instruments Inc. Cooperation of Matlab IDE and Code Composer Studio IDE allow for automatic code generation directly from Simulink blocks, offering a flexible way from system level design and simulation to actual implementation and verification. The wireless (RF) part is based on conventional components. For all multicarrier schemes we explore most of the basic building blocks that constitute them. The implemented testbed is intended primarily for educational demonstration and experimentation purposes offering the means for highlighting and studying several concepts and phenomena regarding not only the modulation schemes but the wireless link as a whole. Typical results concerning the experimental demonstration, evaluation and verification of the testbed are presented.
