LTE-A系统下小区ID盲检算法与ASIC实现研究
Research on Cell - ID Blind Detection Algorithm and ASIC Implementation in LTE - A System
LTE-A系统下,UE与eNodeB的小区同步过程很重要,它能检测得到物理层小区ID并获取时间和频率上的同步,进而才能进行数据通信,因此快速并准确的获取小区ID是一个十分重要的过程。随着协议的不断更新,用户接收端的设计也在不断更新,本文从硬件实现的角度,通过平衡数据运算的快速准确性与硬件成本、面积、功耗等因素,提出一个合理可行的ASIC设计方案,并对其进行UVM验证平台验证。通过与同类模块的对比,本文ASIC设计的面积低8.8%,功耗低9.3%。
LTE-A system, the UE and the eNodeB cell synchronization process is very important, it can detect the physical layer cell ID and access to time and frequency synchronization, and then process data communication, so fast and accurate access to cell ID is a very Important process. With the constant updating of the protocol, the design of the user's receiving end is also constantly updated. This paper proposes a reasonable and feasible ASIC design scheme from the perspective of hardware implementation by balancing the fast accuracy of data operation with hardware cost, area and power consumption. , And UVM verification platform validation. Compared with the same module, ASIC design of this area is 8.8% lower, 9.3% lower power consumption.
