| 摘 要： | 在介绍传统GSM系统频率校正信道（FCCH）侦察捕获算法的基础上，针对在受到强噪声干扰时传统算法的不适用性，提出了基于最大似然匹配的FCCH捕获算法，并进行了计算机仿真验证。结果表明文章提出的算法能够有效克服强噪声干扰，与传统算法相比可以更加准确地捕获FCCH。

| Abstract: | The traditional FCCH capture algorithm in GSM system is introduced in this paper. Under strong interfere, the traditional algorithm exists many disadvantages. Thus, the FCCH capture algorithm based on ML-Matching is advanced. And the algorithm is demonstrated by simulations. Simulation results show that the algorithm advanced by this paper can conquer the strong interfere and can capture the FCCH accurately. |
