首发时间:2008-11-07
摘要:随机接入是移动通信系统中用户与网络建立联系,进行通信的首要步骤,而随机接入前导序列的检测更是随机接入的首要步骤。本文首先对LTE随机接入前导序列的性质和随机接入基带信号进行分析,然后结合picochip多核并行处理器的特点,给出随机接入检测的设计,并分配资源,进行代码实现,最后给出对实现结果的分析。

The design and implementation of Random Access
Abstract:Random access procedure is the first step for UE to communicate with the network in mobile telecommunication systems, and random access preamble sequence detection procedure is the first step of random access procedure. This paper first analyzes the property of the random access preamble sequence and the base band signal of random access. Then according to the characteristic of DSP manufactured by picochip, presents the design of random access preamble sequence detection, allocates the AEs, implements it, and the results are analyzed.
