Description: 对重分配小波尺度谱存在着时、频分辨率不能同时达到最佳及当振动信号中存在着能量较大的噪声时会降低其时频分布可读性的缺陷，提出一种基于参数优化和奇异值分解(SVD)提高重分配尺度谱时频分布可读性的方法。首先利用Shan—
non熵方法优化重分配尺度谱基函数的时间．带宽积(TBP)，克服其时、频分辨率不能同时达到最佳的缺陷，再对重分配尺度谱
进行SVD降噪降低噪声干扰影响，提高时频分布的可读性。最后用该方法对仿真信号和滚动轴承故障信号进行了分析，结果表明该方法的时频聚集性更好，抗噪能力更强，能更有效地识别强噪声背景下的机械故障特征。-Redistribution wavelet scale spectrum for the existence of time and frequency resolution can not be reached when the vibration signal is the best and the existence of large noise energy will reduce the time-frequency distribution readability defects is proposed based on parameter optimization and Singular value decomposition (SVD) to improve spectrum reallocation time-frequency distribution readability scale approach. Firstly, Shan-non entropy method to optimize re-allocation of the time-scale spectral basis functions. Bandwidth product (TBP), to overcome the time and frequency resolution can not achieve the best defect, and then the re-allocation of spectrum SVD scale noise reduce noise interference and improve the readability of time-frequency distribution. Finally, the method and the rolling bearing fault signal simulated signals were analyzed, the results show that the method of time-frequency aggregation better noise immunity stronger, can more effectively identify strong noise ch

Description: Modulation of FSK:
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier wave. The simplest FSK is binary FSK (BFSK). BFSK literally implies using a pair of discrete frequencies to transmit binary (0s and 1s) information. With this scheme, the 1 is called the mark frequency and the 0 is called the space frequency.
Demodulation:
Demodulation is the act of extracting the original information-bearing signal from a modulated carrier wave. The demodulator takes the digital data and, using the staircase maker and the delay unit, creates the analog signal. The created analog signal, however, needs to pass through a low-pass filter for smoothing. It has numerous advantages over AM, such as better fidelity and noise immunity. However, it is much more complex to both modulate and demodulate a carrier wave with FM, and AM predates it by several decades.

Description: 同生命科学中的免疫理论类似，免疫算子也分两种类型：全免疫和目标免疫，二者分别对应于生命科学中的非特异性免疫和特异性免疫。其中，全免疫是指群体中每个个体在变异操作后，对其每一环节都进行一次免疫操作的免疫类型；目标免疫则指个体在进行变异操作后，经过一定判断，个体仅在作用点处发生免疫反应的一种类型。-Life sciences with similar immune theory, immune operator can be divided into two types: full immunity and target immunity, both of which correspond to the life sciences in the non-specific immunity and specific immunity. Among them, the whole population immunity refers to the variability of each individual in the operation, every aspect of its operation once the immune immune type target immunity refers to the individual carrying the mutation operation later, after a certain judge, the individual only in the role of point occurs at one type of immune response.
