| 摘 要： | 分集接收合并技术是抗信号快衰落的一种有效措施。由于等增益合并具有良好的合并效果,并且实现较简单,因此在实际中获得了广泛的应用。针对二重空间分集,分析了一种新的基于锁相环的合并方法。该合并方法利用一个鉴相器就可以实现2路接收信号的频率同步和相位同步,进而可以进行等增益合并。该合并方式可以在不影响性能的前提下简化系统的复杂度、降低同步时间,便于工程实现。

| Abstract: | Diversity combination is an effective technique for anti-channel-fading.Since equal gain combining（EGC）features good combination effect and simple realization,it is widely used in practice.The paper introduces a new combing algorithm based on PLL＇s basic principle for dual space diversity.In this combing method,just one phase discriminator is used to realize frequency synchronization and phase synchronization,then EGC may be conducted.Using this method,the system complexity and synchronization time can be reduced,and it is also easy for engineering realization. |

| Keywords: | symmetry diversity combination PLL phase discriminator frequency synchronization phase synchronization |
