| 摘 要： | 在研究了主公共控制物理信道(P-CCPCH)同步原理、介绍了现有的同步法的基础上,提出了一种新的P-CCPCH同步法.该方法基于SYNC-DL调制相位和载波频偏,可以非常好地克服由于载波频偏而引起的捕获概率降低的现象.仿真结果表明,该方法具有很好的抗载波频偏的性能,且检测概率高,运算量小,操作性强,易于实现.

| Abstract: | On the basis of the P-CCPCH synchronization principle and the existing synchronization methods, a novel P-CCPCH synchronization method based on the modulated phase and the carrier frequency offset of SYNC-DL is proposed. By using this method, the lessened acquisition probability arising from the carrier frequency offset can be easily improved. The simulation results show that this method is well resistant to carrier frequency offset, high in detection probability, small in computational burden, easy to operate and easy to implement. |
