Abstract

The flower and woman are beautiful but Euler's theorem and the symmetry are the best. Shannon applied his theorem to information and communication based on Euler's theorem. His theorem is the root of wireless communication and information theory and the principle of today smart phone. Their meeting point is $e^{-SNR}$ of MIMO(multiple input and multiple output) multiple antenna diversity. In this paper, Euler, who discovered the most beautiful formula($e^{{\pi}i}+1=0$) in the world, briefly guided Shannon's formula ($C=Blog_2(1+{\frac{S}{N}})$) to discover the origin of wireless communication and information communication, and these two masters prove a meeting at the Shannon limit, It reveals something what this secret. And we find that it is symmetry and element-wise inverse are the hidden secret in algebraic coding theory and triangular function.

세상에 꽃고 여자도 아름답지만 오일러 공식과 대칭이 가장 아름답다. 샤논은 무선통신과 정보이론이 뿌리가 되는 샤논 정리를 오일러 정리에 기반해 정보와 통신에 응용했고, 오늘날 Smart Phone의 원리다. 그들의 만난 점은 MIMO(multiple input and multiple output) 다중안테나 다이버시티가 $e^{-SNR}$ 이다. 본 논문에서는 세상에서 가장 아름다운 공식 $e^{{\pi}i}+1=0$를 발견한 오일러와 무선통신과 정보통신을 탄생시킨 $C=Blog_2(1+{\frac{S}{N}})$을 발견한 샤논의 공식을 간단히 유도하고 이 두 거장은 샤논 한계(Shannon limit)에서 만남을 증명하고 숨어있는 비밀이 무엇인가를 밝힌다. 또한 대수학코딩이론(Algebraic coding theory)와 삼각함수 속에 숨겨진 비밀은 대칭(symmetric)과 Element-wise Inverse가 됨을 발견한다.
