Abstract:

The spread spectrum property obscuring in traditional OFDM system is presented.By decreased subcarriers using in OFDM system,the spread spectrum property in OFDM system is discovered.The spread spectrum performance in OFDM system is analyzed using of traditonal spread spectrum systems theory.It is shown that the OFDM system has as good a spread spectrum performance as traditional spread spectrum systems,and can be used to build spread sprectrum systems.

Key words: OFDM;spread sprectrum property;subcarrier
