多通道并行TD-LTE小区搜索架构设计与FPGA实现
Design and implementation of multi-channel based parallel cell search in TD-LTE networks using FPGA
摘要
Abstract
The mobile terminal is connected with the network through the cell search.In order to do the cell search efficiently in time division long term evolution (TD-LTE) networks, a multichannel based parallel cell search architecture is proposed using field programmable gate array (FPGA).Compared with the traditional processing mode of digital signal processing (DSP), the speed and area are considered in this paper whose main work is to design a systematic cell search scheme and to implement the system on hardware platform.The proposed scheme optimizes the cell search structure, and the implementation cost is reduced through a parallel multiplier based serial correlation detection and dynamic threshold configuration.Meanwhile, the Modelsim tests and corresponding experiments are conducted on Altera's EP4SGX230KF40C2 chip.Experimental results show that the proposed scheme can well satisfy the requirement for processing speed and the accuracy of data in TD-LTE networks, and it also outperforms the traditional DSP based processing scheme.It can be applied to the practical project.关键词
