三、BCH码的代数原理 前面讨论的BCH码所使用的素数、余数等,在代数中,有与之相对应的素因式和余式等用文字x表示的多项式。余式就是BCH码的配位码多项式,因而有人把BCH码叫多项式编码。 在古典代数中,x表未知数,有演算值;而在近世代数里,x还是表明状态和位置的文字符号。设由单项式组成的多项式为:
Third, BCH algebraic principle BCH code discussed earlier using the prime numbers, the remainder, etc., in the algebra, there are corresponding prime factors and the remainder of the text with a polynomial x. The remainder is the BCH code coordination code polynomial, so someone called the BCH code called polynomial coding. In classical algebra, the x-table is unknowns and has the calculus value; whereas in modern algebra, x is also a literal symbol that states and positions. Let the polynomial consisting of a monomial be:
