IMPLEMENTING AN OFDM SYSTEM ON HARDWARE

Abstract

Recently, OFDM technique has been applied to many digital communications systems such as DVB-T, WiFi, WiMAX and MIMO systems. OFDM can send multiple high-speed signals by using orthogonal carrier frequencies. In addition, OFDM technique can combat inter-symbol interference (ISI) and inter-channel interference (ICI). Therefore, OFDM has been an essential  technology in high-speed communications. The aim of this project is to implement the base-band OFDM system on hardware exploiting FPGA-based DSP Development Kit and DSPBuilder® software from Altera®. The results can be used for training purpose and for a further development of OFDM-based communication systems.
