人类文明的发展离不开沟通交流,随着时代的快速进步,人与人的距离越来
越远,而通信事业的发展使得人与人的沟通越来越便捷,思念不再是“但愿人长
久,千里共婵娟”的美好祝愿。但是,在忙碌的快节奏时代,我们仅仅满足于电
话两头的问候吗?不是的,信息的时代,我们更希望每时每刻以不同形式与牵挂
的人进行同时,世界之大的进展,足不出户知晓千里。于是,我们进入更快更广
的 4G 时代。
研究背景
4G 的到来,让我们认识到通信的奇妙,然而我们不能满足于依靠吸取别人
的智慧而进步,中国在发展,通信网络自然不能落后,创新是我们的必然要求,
综合中国当前的移动网络技术 3G 系统中 TD-SCDMA 占据重要的地位,使用中
国移动网络的用户量也占据国内人数的极大部分。4G 网络发展如何从 3G 网络
平滑过渡等因素出发考虑,TDD 技术的 L
