Study and performance simulation analysis of OFDM systems

There exist severe problems in wireless communication systems, such as frequency selective fading, fast fading and slow fading, all sorts of noise interference and ICI result of multi-path fading. To tackle the problems, many new techniques have been on the way of research. OFDM is one of them. This paper has investigated this technique in great detail. In combined with digital communication technique and the typical model of OFDM system, it has designed and simulated an artificial base-band OFDM system to analysis its function, and the results of simulation is given in the end.
