离散傅利叶变换 meaning in English
discrete fourier transform
Examples
- After the system has been synchronized , we first use the least square method to make channel estimation , then separate the channel response information from the channel noises by dft . a weighting function based on the minimum mean square error ( mmse ) criteria can be applied to the time domain channel impulse response
在系统同步条件下，首先使用最小平方方法来估计信道响应，然后利用离散傅利叶变换的性质把信道响应信息和信道噪声分离，并在时域按最小均方误差准则做加权处理。
