信息编码技术及应用

``Information coding is the process of converting information into a format that can be easily transmitted and stored by a computer or other electronic devices. This involves the use of specific codes, such as binary code or ASCII code, to represent information in a way that can be understood and processed by machines.’’

In Wikipedia, it refers to:

However, information coding can do a lot actively and `` creatively’’, if specific data structures are embedded into coding structures.   Do you know the following phenomenon in ion trap?

 

Similarly but in a different way, one of our interesting findings is that information coding with specific structures can create prior `` beneficial’’ traps in security. For example, when we attempt to research a bit coding scheme to defend against jamming attack, we develop a thresholded cover-free code based encoding/decoding mechanism on random domain to disperse the effect of attack and enhance the decoding process by using group spatial channel features.

The above just show a little and interesting result in coding theory. Welcome more coming into this area. We still have a long way to go
