摘要
LTE中进行随机接入的功能是实现UE和网络的同步,对于UE只有通过随机接入过程与系统上行同步之后,才能被系统调度进行上行传输。针对随机接入信道在LTE中的实现过程以及随机接入中涉及到的具体参数进行了详细研究,并且通过仿真对ZC序列在RACH中的相关特性进行分析,最后结合实际工程应用给出了在飞思卡尔的8157上的实现方式。
The function of random access in LTE is to achieve synchronization of network and UE. Only through random access and uplink synchronization, UE can be scheduled for uplink transmission. The involved parameters of random access chan- nel （RACH） during realization process and random access in LTE are researched in this paper particularly. Through simulation of Zadoff-Chu sequence in RACH, analysis of relevant characteristics and actual engineering application, the implementation mode of Freescale DSP is presented at the end.
