Abstract: An OFDM transceiver based on software defined radio (SDR) techniques is modeled by MATLAB in this paper. The modulated input data using orthogonal subsidiary companies , with carrier frequency 70MHz. After contaminating the signal with noise , and re- sampling – the received signal and convert it to a digital system to extract the original information . Results obtained tend to increase in the signal to noise ratio , and improve the planned constellation of the received signal and bit error rate (BER) of the system decreases to zero when the S / N ratio greater than 12dB. FPGA to implement a complete SIMULINK model first and then generate HDL code and DSP design tool from XILINX, and the results will be obtained from MATLAB and FPGA be approximately equal.
