信道估计方法和接收机
摘要：
为了在采用波束赋形时提高信道估计值的精度，提供了一种信道估计方法，包括：根据小区特定参考信号来确定小区特定参考信号的信道估计值；根据UE特定参考信号来确定UE特定参考信号的信道估计值；通过使用小区特定参考信号的信道估计值来计算小区特定信道估计值；通过使用小区特定参考信号的信道估计值和UE特定参考信号的信道估计值来估计波束赋形矢量；以及通过将小区特定信道估计值与波束赋形矢量相乘来计算UE特定信道估计值。
摘要（英）：

In order to improve the accuracy of a channel estimation value when using beam-forming, a channel estimation method obtains a channel estimation value of a cell-specific reference signal from the cell-specific reference signal, obtains a channel estimation value of a UE-specific reference signal from the UE-specific reference signal, calculates a cell-specific channel estimation value using the channel estimation value of the cell-specific reference signal, estimates a beam-forming vector using the channel estimation value of the cell-specific reference signal and the channel estimation value of the UE-specific reference signal, and calculates the UE-specific channel estimation value by multiplying the beam-forming vector by the cell-specific channel estimation value.
