摘要
研究了CDMA系统中自适应阵列天线结合相关检测抗干扰技术,并在理论和模拟上对改进前后的抗多址干扰的性能进行了分析对比,验证了当有用信号方向与其他用户的多址干扰方向不同时,新的方法的性能大大优于传统相关检测方法。
In this paper,the combination of an adaptive array antenna and traditional detection for interference suppression in CDMA system is discussed.A new combined method is proposed,and its improvement of performance for multiple Access Interference (MAI) suppression is analyzed and proved in theory and in practice.It is proved that the MAI suppression performance of the new method achieves a greater improvement than the traditional detection only.
