2、进行简要阐述。第二，着重介绍了 WCDMA 系统的网 络结构并且对信道进行了相应地研究(信道的结构、划分及编码等)，并介绍了物理层信号 的处理过程。第三，介绍了小区的选择和重选、切换控制技术和功率控制技术。之后，从 工程项目着手分析了 WCDMA 的业务优化流程，介绍了 WCDMA 业务优化的方法及注意 事项。 最后通过几个 WCDMA 网络优化中路测上的工程实例， 来总结我们在工作中遇到问 题时的解决思路及方法。 WCDMA 系统有着非常广阔的发展前景，对其网络原理及优化的研究也颇为重要，所 以要认真学习理论知识，并且与实践相结合，在工作中注意吸取前人经验教训，充分发挥 自己的能力。 关键词
3、：WCDMA；网络原理；网络优化 II ABSTRACT On January 7th, 2008，China Unicom corporation got the WCDMA license，since then, the construction of 3G began to carry out officially in China. In recent years, being one of the main 3G standards, WCDMA has being a hotspot in the field of communication. In this paper, the
4、 WCDMA network principle and optimization was studied. First of all, the present situation and the advantages of WCDMA were introduced briefly, and refered to some key technologies. The second, the network structure of the WCDMA system and channel was introduced emphatically and research to the chan
5、nels correspondingly(the structure, classifications and coding ways of channel were analyzed), and introduced the process of physical layer signal.The third, the respective selection and re-election for the specific area、 control technologies of switching and power were presented. Then, I am to set
6、out to analyz the business optimization process from the project and the business optimization methods and the matters needing attention of WCDMA. At last, I summerised some thoughts and methods for solving problems that once we encounter in our worklife through several engineering examples that tested on road in WCDMA network optimization. WCDMA system has a huge prospect for development, the research on its network principle and optimization is also very important. So we should learn
