为实现通信的终极目标五个W:任何人(whoever)在任何时间(whenever)任何地点(wherever)与任何他人(whomever)进行任何类型(whatever)的信息交换,则至少通信网的最后一段必须是移动通信系统。由此可见移动通信在现在及未来通信中的重要地位。(communications to achieve the ultimate goal of 5 W : Any person (whoever) at any time (whenever) any location (wherever ) and any other person (whomever) for any type (whatever) the exchange of information, communications network at least the last paragraph must be mobile communication systems. So mobile communications in the current and future communications to the important position.)

pcnn
利用pcnn,每当有一批像素对应的神经元点火,对像素值进行一次修正。第n次点火的所有神经元用矩阵B(n)表示,
已经点火的像素位置标记为‘1’,未点火的标记为‘0’。通过一个3*3的模板滑过B(n),判断若模板内的值全为‘1’或全为‘0’,
则这些像素值不进行处理,否则若模板中心的值为‘1’,则增加该位置的像素值的大小,中心值为‘0’,则减小像素值。该功能由xiugai(B,K)函数实现
Beta取负值来抑制周围的神经元点火,因为输入pcnn(X)的是模糊图像,抑制之后使处理的像素值更加接近原图像的像素值(抑制参数通过试验确定,并不精确)
总之运行结果只是对像素值变化较大的边缘区域进行了像素值的修正。
通过不断调整参数使峰值信噪比有所升高,但是升高得不是太多(Use pcnn, whenever a group of pixels corresponding to the firing of neurons, a correction value for the pixel. Ignition of all the n-th neuron matrix B (n) represents,
Already ignition pixel position labeled 1 , unfired labeled 0 . By a 3* 3 templates over the B (n), determines if the value within the template are all 1 or all 0 ,
These pixel values are not processed, otherwise the value if the template center 1 , then the increase in the size of the pixel values of the position, the center value of 0 , the pixel value is reduced. This function is implemented by xiugai (B, K) function
Beta is a negative value around the element to inhibit neuronal firing, because the input pcnn (X) is a blurred image, the pixel values of inhibition after treatment of the pixel value closer to an original image (suppression parameter determined by experiment, is not exact)
Results only in short run large changes in the edge region of the pixel values of the corrected pixel values.

Only coding parameters of sound generation model
• LPC is an example where parameters are a1, a2, …ak , e(n)
• Music instrument parameters: pitch, loudness, timbre, …Frequency Masking: If a tone of a certain frequency
and amplitude is present, then other tones or noise of
similar frequency cannot be heard by the human ear
• the louder tone (masker) makes the softer tone
The Masking Threshold is used by the audio encoder to
determine the maximum allowable quantization noise at
each frequency to minimize noise perceptibility: remove
parts of signal that we cannot perceive
