LTE-A载波聚合技术研究及在PDCCH盲检测中的应用

Carrier Aggregation Technology and Application in PDCCH Blind Detect of LTE-A

阐述了载波聚合关键技术的最新进展,具体介绍了载波聚合技术在PDCCH盲检测中的应用,以及支持跨载波调度和不支持跨载波调度两种方式下的盲检测方法和各自优缺点。通过C语言搭建链路,对两种调度方式的性能进行了仿真,为LTE-A系统的实现提供了理论依据。

This article expounded the latest progress of key technology about carrier aggregation, intro- duced in detail the carrier aggregation technology application in the PDCCH blind detect of LTE-A, introduced the blind detect methods and their advantages and disadvantages under the two ways of scheduling support across carrier and no support scheduling across canner. With the performance simulation of the two kinds of scheduling by establishing link with C language, a theoretical basis for the practical realization of LTE-A systerm is provided.
