研究表明超高斯分布更加贴近语音信号的实际分布,然而语音信号很难用单一的概率密度
函数准确描述,针对这一情况,提出了一种用超高斯混合模型对语音信号幅度谱建模的新方法,并推导了
基于此模型的幅度谱最小均方误差估的估计式。仿真结果表明:与传统的短时谱估计算法相比,该算法不
仅能够进一步提高增强语音的信噪比,而且可以有效减小增强语音的失真度,提高增强语音的主观感知
质量。 (Recent research indicates that the speech spectral amplitude distributions could
be fairly described with super-Gaussian probability density function. However, the complexity
of speech signal determines that the distribution statistics ofspeech signal could not be well
described by single simple function. Thus a super-Gaussian mixture model for speech spectral
amplitude is proposed, and with this model, a minimum mean-square error (MMSE) estimator for speech
signals spectral amplitude is derived. The simulation results show that this algorithm based on
Gaussian and super-Gaussian speech model could achieve better noise suppression and lower speech
distortion as compared with the conventional short-time spectral amplitude estimation algorithm. )

将输入d进行扩张,方法是在d的每个数据中插入M-1个零值。
如输入d=[1,2,3,4] M=3
输出out=[1 0 0 2 0 0 3 0 0 4 0 0](To expand the input d, the method is to insert each data d, M-1 zero value. If the input d = [1,2,3,4] M = 3 output out = [1 0 0 2 0 0 3 0 0 4 0 0])

The demand of high data rate services has been increasing very rapidly and there
is no slowdown in sight. We know that the data transmission includes both wired
and wireless medium. Often, these services require very reliable data transmission
over very harsh environment. Most of these transmission systems experience much
degradation such as large attenuation, noise, multipath, interference, time variance,
nonlinearities and must meet the finite constraints like power limitation and cost
factor. One physical layer technique that has gained a lot of popularities due to
its robustness in dealing with these impairments is multi-carrier modulation technique.
In multi-carrier modulation, the most commonly used technique is Orthogonal
Frequency Division Multiplexing (OFDM)
