摘　　要：为了提高CDMA通信系统多址能力,降低扩频码同步的虚警概率和捕获时间,分析讨论了截短Gold序列的相关特性和平衡特性。通过对截短前后、不同序列周期、不同截短长度的截短Gold序列的性能仿真,分析了作为地址码的截短Gold序列的相关特性和平衡特性对通信系统多址能力的影响。仿真结果表明:在满足系统对序列性能要求的条件下,序列级数越大,截短比例越小。In order to improve the multi-address ability of the CDMA communication system, reduce the probability of fake alarm and the capture time, the correlation and balance characteristics of the truncate balance Gold code were analyzed and discussed. The characteristics of the code were emulated and compared before truncating and after truncating, in different period, in different length. The influence on the rnultiaddress characteristic of communication system was analyzed. The result shows that the truncate proportion becomes smaller as the grade becomes bigger in the condition of meeting the system requirements.
