信号处理方法及设备
相关申请的交叉引用
本申请主张在2019年11月14日在中国提交的中国专利申请号No.201911112299.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及通信技术领域，尤其涉及一种信号处理方法及设备。
背景技术
近年来高速铁路的发展非常迅速，世界范围内的高铁速度已普遍达到250km/h，有的甚至已经超过了350km/h。高铁运行速度的加快给高铁移动通信带来一系列的影响，例如，在高速移动场景下，用户与基站之间的相对速度非常高，这会产生较大的多普勒频偏，若不采取有效的措施抑制多普勒效应，则会严重影响通信系统的性能。因此，终端需要对信号的多普勒频偏进行估计。
参见图1，1个室内基带处理单元(Building Base band Unit，BBU)通过光纤连接至3个射频拉远头(Remote Radio Head，RRH)，每个RRH有2个不同方向的天线面板。
每个RRH发送的信号完全相同，由于信号到达终端(例如，用户设备(User Equipment，UE))的路径不同，在UE侧接收到的是多路不同延迟的“多径”信号，UE基于跟踪参考信号(Tracking Reference Signal，TRS)估计多普勒(Doppler)频率。
图中2个RRH从2个不同的方向发来数据，两个信道的Doppler频率完全不同，甚至是相反的。
因此，对于UE而言，2个RRH发送的TRS，类似于收到两条多普勒完全不同甚至相反的多径，用这个TRS估计的多普勒频率非常不准，并不能体现两条径的真实Doppler频率。

继续参见图4，RRH2根据基站之间交互减去Δf1，RRH2在频点fc-Δf2向UE发送PDCCH/PDSCH承载的信号，UE在频点fc接收到PDCCH/PDSCH承载的信号。
