在为误差纠错编码设计回路时,在第二有限域上进行的多项式除法有一定的重要性。这类除法运算可以利用线性反馈移位寄存器(即LFSR)来完成。例如用左移位寄存器的简单回路可以进行函数f(x)模p(x)的运算。其主要优点是运行f(x)模p(X)的回路(简称MOD回路)与函数p(X)无关,且相同的回路还可用于由另一个同次多项式来进行的除法,只需改变 Polynomial division over the second finite field is of some importance when designing the loop for error correction coding. This type of division can be done using a Linear Feedback Shift Register (LFSR). The function f (x) modulo p (x) can be performed, for example, with a simple loop of left shift register. Its main advantage is that the loop running f (x) mod p (X) (referred to as the MOD loop) has nothing to do with the function p (X) and the same loop can be used for the division by another polynomial of the same degree,
