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)

faultysignal_with_noise
1. 构造含噪音的振动信号 faultysignal_with_noise，
2. 利用小波变换 Wavelet transform去噪，小波包 Wavelet packet transform 变换去噪，
3. 把两种去噪后的信号，分别用STFT ,FFT ,小波变换三种方法进行错误诊断(1. the vibration signal faultysignal_with_noise, which contains noise, is constructed.
2. using wavelet transform Wavelet transform denoising, wavelet packet Wavelet packet transform transform de-noising,
3. the two kinds of denoising signals are diagnosed by three methods, STFT, FFT and wavelet transform respectively.)
