Windowing
In this letter, we propose anovel family of windowing
technique to compute mel frequency cepstral coefficient (MFCC)
for automatic speaker recognition from speech. The proposed
method is based on fundamental property of discrete time Fourier
transform (DTFT) related to differentiation in frequency domain.
Classical windowing scheme such as Hamming window

说明： 6. 在三条径的瑞利信道中，对于OFDM：
(1) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。
(2) 设频率已同步，请设计OFDM一种具体的采用循环前缀进行时间同步方法，用Simulink进行仿真，画出比特信噪比与捕获概率的关系曲线。
(3) 设时间已同步，请设计OFDM一种具体的采用循环前缀进行频率同步方法，用Simulink进行仿真，画出比特信噪比与频率同步误差的关系曲线。
