Abstract

This paper deals with the implementation of OFDM demodulator Digital Radio Mondiale system DRM. The article is aimed to design a 64-QAM demodulator using the software tools “System Generator for DSP” from Xilinx and MATLAB-Simulink [1]. The theoretical performance has been verified by simulations. Moreover, demodulator´s circuit was subsequently implemented by the programmable elements into Field-Programmable Gate Arrays (FPGAs). Finally some testing measurements were made to prove the practical function in the real conditions.
