摘要
多载波频率分集扩展频谱码分多址通信（ＦＤ／ＳＳＭＡ）系统是一种基于多载波传输、利用与直接序列扩展频谱码分多址系统（ＤＳ／ＳＳＭＡ）的时间频率对偶关系而提出的新的扩展频谱多址方案．本文给出了ＦＤ／ＳＳＭＡ系统的基本原理，分析了在加性高斯白噪声信道下ＦＤ／ＳＳＭＡ的多址性能和抗单频干扰能力，并通过高斯近似法和ＭｏｎｔｅＣａｒｌｏ模拟方法得到了系统的平均误比特率．
Based on the theory of orthogonal multicarrier technique and the 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 principle of FD/SSMA system is given.The ability against jamming and multiple performance 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 Gaussion approximation and Monte Carlo simulating methods.
