FIR低通滤波器设计,表达得还比较详细，可以借鉴参考(FIR low-pass filter design, is also expressed in more detail, you can learn from the reference)

Compute the matrix of mel filter coefficients given the sampling frequency, the length of the FFT and the number of desired mel filter channels.

可以对信号进行短时傅里叶变换，也可以对反射系数序列进行短时傅里叶变换(STFT)

OFDM链路级的仿真器场景是单小区单用户，信号从发送端发送，在接收端进行信号估计。估计误差可以从接收和发送信号的不同得到。仿真器的输出是BLER/BER vs SNR。(OFDM Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table。)

说明：  液晶空间光调制器的原理和具体的应用以及相关的算法描述(Liquid crystal spatial light modulator of the principles and specific applications)

交会对接采用的Lambert算法，为《轨道动力学与控制》大作业源码，可直接运行(Lambert algorithm)

uses the message signal X to modulate the carrier frequency Fc (Hz) and sample frequency Fs (Hz), where Fs > 2*Fc. FREQDEV (Hz) is the frequency deviation of the modulated signal.

这个例子阐明了发生在时变系统中的频谱扩展，系统的带通输入时在某个频率上的音频信号(This example illustrates the system occurred in the time-varying spectrum expansion of the system' s band-pass input on a frequency of audio signal)
