摘要： An egg beater includes a seat, and a stirring net mounted on the seat and including a plurality of primary stirring strips and a plurality of secondary stirring strips. Each of the primary stirring strips has a surface formed with a helical groove. Thus, the air is introduced into the dough rapidly and largely by guide of the helical grooves of the primary stirring strips during rotation of the stirring net, so that the air input introduced into the dough is greatly enhanced, thereby decreasing the stirring time of the egg beater.

摘要： A fine symbol timing synchronization method and apparatus in an orthogonal frequency-division multiplexing (OFDM) system are provided. The fine symbol timing synchronization method finds a path with a minimum mean square error (MMSE) as a first path among a plurality of paths, and a formula of the mean square error (MSE) used by the method is a simplified formula of the original MSE formula with low calculation complexity. Therefore, the time required by the fine symbol timing synchronization method is short, and a correct first path can be found, so as to lock a starting position of a fast Fourier transform (FFT) window on a starting position of a symbol signal of the correct first path.
摘要翻译：提供了一种正交频分复用（OFDM）系统中的精细符号定时同步方法和装置。精细符号定时同步方法在多个路径中找到具有最小均方误差（MMSE）作为第一路径的路径，并且该方法使用的均方误差（MSE）的公式是原始具有低计算复杂度的MSE公式。因此，精细符号定时同步方法所需的时间短，可以找到正确的第一路径，以便将快速傅立叶变换（FFT）窗口的开始位置锁定在正确的第一条路径。
