| Through the evolving of 3G system,the LTE system provides users more powerful data and service.However,if the Mobile Communication wants to access to the network and use the wireless network resources,they must go through the process of random access.The main purpose of random access is to get uplink synchronization.In this paper,the protocol about Random Access in LTE,the process of Random Access,the algorithm of physical Random Access and the use of FPGA implementation has been studied.These are given to achieve a better understanding about RACH in LTE.Focus on the algorithm of the producing of the Random Access preamble and the implementation of FPGA which is based on the algorithm.In this paper,we build a simulation platform of LTE Random Access.Compare the data between the one which is produced by the platform and the one which is simulated by software.By comparing the results to determine whether the capabilities is achieved.And in the course of the simulation,we can build further understanding of the entire process of Random Access. |
