Deployment of 5GHZ real-time simplex wireless SISO- and MISO-OFDM transmission using matlab and the TMS320C6713 DSKS

In this paper we describe the design and deployment of a real-time simplex wireless SISO- and MISO-OFDM transmission setup on 5GHz employing two TMS320C6713 DSP Starter Kits (DSKs) as the baseband transmitter and receiver. The baseband system level design is done using Matlab/Simulink and the deployment on the TMS320C6713 DSKs is performed by means of IDE link via automatic code generation directly from Simulink blocks, offering a flexible way from system level design and simulation to actual implementation and verification. The wireless part is built based on conventional components and employs two transmit and one receive antennas. For both SISO and MISO, all the basic building blocks are comprised also including Maximum Likelihood (ML) synchronization based on the cyclic prefix as well as sampling clock frequency offset estimation and compensation. The implemented test-bed is intended primarily for educational demonstration and experimentation purposes for highlighting and studying several concepts and phenomena not only regarding the modulation schemes but the wireless link as a whole. Typical results for the experimental demonstration and evaluation of the system are presented.
