Abstract

In this paper, we present an implementation of a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system based on the multi-core Texas Instrument (TI) C64x+ digital signal processor (DSP). The system is implemented by employing real time data exchange (RTDX) and serial rapid input/output (SRIO) techniques for communication interfaces between personal computer (PC) and DSP. Received signals obtained by the DSP processing are visualized to verify the implemented system. Furthermore, this study is concerned with bit error rate (BER) performance and the computational complexity of system written in C/C++.
