说明： 离散信号Gabor展开的理论及实现颇为繁琐。其中包括离散Gabor变换的标架理论、周期序列的离散Gabor变换、非周期序列的离散Gabor变换以及各种快速算法等。此程序给出给出了一个线性调频信号的Gabor变换。(Gabor expansion of discrete signals and the realization of the theory is quite cumbersome. Including discrete Gabor transform frame theory, the periodic sequence of discrete Gabor transform, non-periodic sequence of discrete Gabor transform and a variety of fast algorithms. This procedure gives a linear FM signal is given the Gabor transform.)

使用低通滤波器从含有噪声的信号中提取有用的正弦波
(见实验指导书 实验九 数字滤波器中的第一题)
目的：用数字滤波器从含有高频噪声的采样数据中提取正弦信号。
要求：①输入信号为一正弦波，并加入一个白噪声的干扰来模拟信号传输中的随机干扰信号（用以模拟含有噪声采样序列）。
（模拟含有噪声采样序列具体可用正弦波信号叠加高频噪声来实现，为了使滤波效果明显，本实验的高频噪声是用高频均匀分布白噪声（Uniform）通过Butterworth高通滤波器过滤生成的，高通滤波器的截止频率设为10倍输入信号频率。）
②在程序中设计一个低通巴特沃斯滤波器，以滤除信号中的噪声分量，提取输入的正弦波信号 。
③可调节信号滤波器的截止频率和阶数，可显示滤波前与滤波后的时域信号。
④给出滤波前与滤波后的频谱特性的显示。

carrier-modulation
多载波调制(Multicarrier Modulation)采用了多个载波信号。它把数据流分解为若干个子数据流，从而使子数据流具有低得多的传输比特速率，利用这些数据分别去调制若干个载波。所以，在多载波调制信道中，数据传输速率相对较低，码元周期加长，只要时延扩展与码元周期相比小于一定的比值，就不会造成码间干扰。因而多载波调制对于信道的时间弥散性不敏感。多载波调制可以通过多种技术途径来实现，如多音实现(Multitone Realization)、正交多载波调制(OFDM)、MC-CDMA和编码MCM(Coded MCM)。其中，OFDM可以抵抗多径干扰，是当前研究的一个热点。(Multi carrier modulation (Multicarrier Modulation) uses multiple carrier signal. It decomposes a data stream into a plurality of sub data stream, so that the sub data stream transmission bit rate is much lower, respectively to a plurality of carrier modulation using these data. )
