LTE和LTE-Advanced关键技术探究

摘要

作为新一代宽带业务的国际标准（4G时代），LTE网络采用了许多新技术。它采用扁平化网络构架的方式进行设计，包括一些聚合多载波、异构网络、中继、多点发送、MIMO和先进的抗干扰管理等技术。这些技术极大地提高了小区边缘用户的一些性能，使小区的信息传输速率和系统容量得以增加。%As the international standard of a new generation of broadband services (4G times), LTE network adopts many new techniques. It adopts flat network architecture, including polymerization multi carrier, heteroge-neous network, relay, multicast, MIMO and the advanced anti interference management techniques. These tech-niques greatly improve the performance of cell edge users and increase the cell information transmission rate and the system capacity.
