Real Time Implementation of OFDM system on DSP Processor

Dr. Seema Verma, Pawan Sharma

Orthogonal Frequency Division Multiplexing (OFDM) technology has been adopted by a variety of standards. This technology was chosen due to its robustness at high data rates in a frequency selective multipath channel. This paper describes a real-time implementation of a half-duplex OFDM system using Matlab software simulink, DSP processor TMS320C6713 and Code Composer Studio. In this approach, MATLAB and Simulink make the transition from theory to application easy and enjoyable. The hardware interface converts the baseband signal from the PC to the DSP Processor. Basic transmission and reception performances are evaluated in real time using Real Time data Transfer (RTDX).
