信道估计的方法及装置制造方法及图纸

本发明专利技术实施例提供了一种信道估计的方法及装置，涉及通信技术领域，方法包括：对接收信号中的数据载波进行初始信道估计以及gamma因子消除处理后得到数据载波的信道估计值；根据数据载波的信道估计值，对接收信号中的空载波和导频载波进行填补处理后得到空载波和导频载波的信道估计值；获取接收信号的调制方式，并根据调制方式确定滤波器的抽头系数；根据确定的抽头系数在滤波器中对数据载波的信道估计值以及空载波和导频载波的信道估计值进行频域滤波；对滤波后的数据载波的信道估计值进行gamma因子添加处理后，得到最终的数据载波的信道估计值。本发明专利技术在LS算法的基础上频域滤波降低信道误差，降低了操作的复杂性以及时延，提高了信道估计的效率。

Method and apparatus for channel estimation

The embodiment of the invention provides a method and apparatus for channel estimation, which relates to the technical field of communication, the method includes: the estimated value of the initial channel estimation and channel gamma factor to eliminate processed data carrier for data carrier in the received signal; according to the estimated channel data carrier, the received signal in space and carrier pilot carrier to fill the channel estimation value is obtained after the treatment of air carrier and pilot carrier; gain modulation of the received signal, and to determine the filter tap coefficients according to the modulation mode; according to the tap coefficient determined in the filter channel on the data carrier estimation and channel for air carrier and pilot carrier estimation in frequency domain filter; channel on data carrier filtered estimates of the gamma factor was added after the channel data carrier of the final estimate Value. Based on the LS algorithm, the frequency domain filtering reduces the channel error, reduces the operation complexity and delay, and improves the efficiency of the channel estimation.
