The estimated channel frequency response can improve the performance of the iterative receiver.
这样估计的信道频响可以提高软信息迭代接收的性能。
The proposed system is designed to work with noisy input speech and unknown channel frequency response.
我们所设计的系统为的是工作在噪声化输入语音和不明信道频率响应中的。
The LS channel estimation of OFDM systems can be viewed as a noisy observation of the true channel frequency response, so the noise component can be compressed through subspace projecting.
OFDM系统的LS信道估计可看作真实信道频率响应的一个有噪观察值，因此可采用子空间投影方法对噪声进行压缩。
