随着电子技术的不断发展,出现了大规模、超大规模集成电路,这大大提高了计算机的速度和容量。同时,为编码的实现方法提供了有力的工具,并使得Zq上的序列生产成为可能。本文通过文献[1]中定义的因子关联图Γf.在Γf中定义了示性函数,给出了由示性函数构造无向树部分图,并通过无向树部分图来构造M序列的方法。在文中,本文推广了文献[2]中距离函数的概念,给出了几种新的示性函数,还推广了文献[1]中的方法,从纯轮换及补轮换的因子护联图出发给出了M序列的构造力法和例子。
With the continuous development of electronic technology, there have been large-scale, very large-scale integrated circuits, which greatly increased the speed and capacity of the computer. At the same time, it provides a powerful tool for the realization of coding and makes the sequence production on Zq possible. In this paper, the definition of the factor function in Γf is defined by the factor correlation graph Γf in [1], and the method of constructing an undirected tree part graph by an explicit function is given. . In this paper, the concept of distance function in literature [2] is generalized and several new explicit functions are given. The method in [1] is also generalized. Starting from the factor protection diagram of pure rotation and replacement rotation The construction method and example of M sequence are given.
