摘要
LTE小基站可改善室内外深度覆盖、增加网络容量、提升用户感知,可广泛用于楼宇中或密集区安装的小型基站。目前小基站的样机开发也正在各个通信公司如火如荼的开展着,文中以飞思卡尔提供的BSC9132芯片为硬件平台来开发LTE小基站。本文将用一块该芯片实现LTE物理层基带处理算法,对物理层链路可用算法实现也用该芯片基带处理硬件加速器来实现。在驱动模块设计必须在"软件"与"算法"各自的特性之间进行折中与妥协。要考虑算法的有效性同时考虑软件的可移植性,效率要求与软件特性相冲突时,效率优先。
LTE small basestation can improve the depth of coverage, increase network capacity, improve user perception can be widely used in small buildings or dense area of the base station installed. Currently the prototype development of small basestation are also various communications companies to carry out a full swing, following Freescale provided BSC9132 chip hardware platform to develop LTE small basestation. This article will achieve LTE baseband algorithm with a physical layer of the chip, the physical layer link is available algorithm is also used in the baseband chip hardware accelerators to achieve. Modular design of the drive must be between ＂software＂ and ＂algorithm＂ individual characteristics compromise and compromise. To consider the effectiveness of the algorithm taking software portability, when efficiency requirements conflict with software features, the efficiency priority comes first.
