| 摘 要： | 本文分析在加性高斯噪声信道下ＦＤ／ＳＳＭＡ系统采用三种不同的用户地下码型时的系统容量及平均误比特性能。理论分析和模拟结果表明，对ＦＤ／ＳＳＭＡ系统而言、采用正交码要从采用伪随机码或Ｇｏｌｄ序列时系统具有更好的多址能力。

| Abstract: | The capacity and performance of FD/SSMA system over the additive Gausian white noise channel is ana lyzed when three kinds of codes are chosen respectively. It is shown by analysis and simulation that the better performance of multiple access will be obtained for FD/SSAM system which the Walsh codes are chosen, compared with those system in which the random codes or Gold codes are chosen. |
