中文摘要	提出了一种改进的正交多载波同步 DS/CDMA系统。该检测器占用频谱与单载波的频谱相同 ,满足 CDMA系统频谱利用率高的特点。利用降低码片速率有效降低每路信号占有的带宽 ,将每路信息的比特分配在不同的调制载波上 ,减少了各路信号间的多址干扰。分析了系统的工作原理和系统性能。该系统结构简单 ,计算复杂度低 ,工程实现容易 ,且具有较强的抗多址干扰和“远 -近”干扰能力。; An improved orthogonal synchronous multi-carrier DS/CDMA is proposed in this paper. Spectrum characteristic of improved multi-carrier DS/CDMA is the same as single-carrier detector, conforming with spectrum characteristic of CDMA. Frequency width is compressed by decreasing signature-code speed and using bit-signal modulates by different carrier so as to decrease multi-user interference. The principle of this system is analyzed and the performance of the system is displayed. This improved system has a simple structure and low complexity of calculation. It can be realized easily in engineering and preferably eliminates MAI and near-far resistance.; 【作者单位】集美大学信息工程学院福建厦门361021；【作者英文名】CHEN Chao-yang (Institute of Information Engineering, Jimei University, Xiamen 361021, China)
