| Abstract: | Based on the theory of orthogonal multicarrier technique and time/frequency duality with DS/SSMA system ,a new scheme of spread spectrum system ,named Frequency Diversity Spread Spectrum Multiple Access System (FD/SSMA) is proposed . The ability against jamming in FD/SSMA system over the additive Gaussion white noise channel(AGWN) is analyzed ,and the average probability of error bit is given by means of the Monte Carlo simulation. |
