摘要
在目前通信领域,LTE技术应用十分广泛。为进行下行信道估计,LTE协议定义了多个天线端口的RS信号。由于每个天线端口的RS映射方式都不一样,这给RS的解扰实现带来了一定的困难。论文根据每个天线端口RS的映射规律,通过在解扰前对符号计数进行预处理、对RS的位置检测以及序列的产生进行优化,提出一种适合ASIC实现的解扰方法,在通信领域有很强的应用价值。
LTE technology has a widely application in modern communication domain. For doing channel estimation, several antenna ports are defined by its associated reference signal in LTE protocol. Because of the differences among the RS mapping for each antenna port, it＇s difficult to implement the descramble operation. This paper proposes a method for descramble according to the symbol number pre-proces- sion and the optimization of the RS position detection and sequence generation which is easy for ASIC implementation and has a widely appli- cation.
