摘要
分析了ＦＳＫ调制方式与ＣＤＭＡ结合起来构成新的ＦＳＫ／ＣＤＭＡ通信系统的通信特性、多址特性、同步跟踪特性等．结果表明，该系统既体现ＣＤＭＡ的优点，又保留了ＦＳＫ的简捷、方便的特性．还对ＭＦＳＫ／ＣＤＭＡ、ＦＭ／ＣＤＭＡ通信系统性能作了分析．最后，给出了ＦＳＫ／ＣＤＭＡ通信系统的实现方法及相应的实验结果．
FSK modulation has been widely used in communication systems due to its simplicity, low cost and easy to implementaton. CDMA is a multiple access communication technique with high efficiency and interference rejection. A new communication system combining FSK and CDMA techniques is proposed in this paper. Some detailed analyses of system performence, multiple access ability, syschronizing and tracing characteristics are presented.The results show that the proposed system possesses both CDMA′s advantages and FSK′ characteristics. At the end,the paper discusses the implementation and some experiment results of this system.
