首发时间:2015-11-04
摘要:LTE-A采用载波聚合、高阶MIMO等技术以增加系统容量,提高峰值速率,降低延时。相比于LTE系统,载波聚合增加了L2处理复杂度,高阶MIMO增加了物理层运运算量。为保证系统整体实时性的要求本文重点研究了PDCCH处理过程提出一种改进处理方法,降低信息冗余度,减小运算量。仿真结果显示,与传统方法相比本方法有效提升PDCCH信道整体的处理速度。

A Fast Implement of PDCCH Channel in LTE/LTE-A System
Abstract:LTE-A uses carrier aggregation, high order MIMO etc. to increase system capacity, improve peak rate,and reduce latency. Comparing to LTE, carrier aggregation increases the complexity of L2 processing, and high order MIMO increases the physical layer processing. In order to guarantee the real-time performance of the system, this paper mainly studies the process of PDCCH, and proposes an improved method to reduce the redundancy of information and the amount of computation. Simulation results show that this method can effectively improve the processing speed of PDCCH channel as compared with the traditional method.
