OFDM System Design and Simulation Based on Matlab

The basic principles of Orthogonal Frequency Division Multiplexing(OFDM)technology are introduced.Based on the OFDM system model proposed and by means of Matlab simulation, the total system is simulated under the conditions of the Gaussian white noise channel, and the bit error rate performance curve is thus obtained. The simulation result shows that the OFDM system has a strong capacity of resisting disturbance and can correctly demodulate the transmitted data
