通信工程
通信工程通信工程(也作信息工程，电信工程，旧称远距离通信工程、弱电工程)是电子工程的一个重要分支，同时也是其中一个基础学科。
该学科关注的是通信过程中的信息传输和信号处理的原理和应用。
一、专业简介通信专业实验室通信工程（Communication Engineering）专业是信息科学技术发展迅速并极具活力的一个领域，尤其是数字移动通信、光纤通信、Internet网络通信使人们在传递信息和获得信息方面达到了前所未有的便捷程度。
通信工程具有极广阔的发展前景，也是人才严重短缺的专业之一。
本专业学习通信技术、通信系统和通信网等方面的知识，能在通信领域中从事研究、设计、制造、运营及在国民经济各部门和国防工业中从事开发、应用通信技术与设备。
毕业后可从事无线通信、电视、大规模集成电路、智能仪器及应用电子技术领域的研究，设计和通信工程的研究、设计、技术引进和技术开发工作。
近年来的毕业生集中在通信系统、高科技开发公司、科研院所、设计单位、金融系统、民航、铁路及政府和大专院校等。
本专业本着加强基础、拓宽专业、跟踪前沿、注重能力培养的指导思想，培养德、智、体全面发展，具有扎实的理论基础和开拓创新精神，能够在电子信息技术、通信与通信技术、通信与系统和通信网络等领域中，从事研究、设计、运营、开发的高级专门人才。
二、专业综合介绍引子细心的你是否留意到，十年前港台电影中黑帮大佬手里可以用来砸人的“大哥大”，早已变得如此纤细轻巧、色彩缤纷，并且飞入寻常百姓之手；从前只有数月飞鸽传书才能联系的国外亲友可以用简单方便快捷的伊妹儿（E-mail）互致问候、即时聊天，甚至装上摄像头开个网络会议！这一切都应该归功于通信工程（Communication Engineering）技术的迅猛发展。
如果让科学家们选出近十年来发展速度最快的技术，恐怕也是非通信技术莫属。
那么让我们来多了解一下这个年轻而又略显“神奇”的专业吧。
专业简介通信技术是以现代的声、光、电技术为硬件基础，辅以相应软件来达到信息交流目的。
